Background: The microbial population of the intestinal tract and its relationship to specific diseases has been extensively studied during the past decade. However, reports characterizing the bile microbiota are rare. This study aims to investigate the microbiota composition in patients with pancreaticobiliary cancers and benign diseases by 16S rRNA gene amplicon sequencing and to evaluate its potential value as a biomarker for the cancer of the bile duct, pancreas, and gallbladder. Results: We enrolled patients who were diagnosed with cancer, cystic lesions, and inflammation of the pancreaticobiliary tract. The study cohort comprised 244 patients. We extracted microbiome-derived DNA from the bile juice in surgically resected gallbladders. The microbiome composition was not significantly different according to lesion position and cancer type in terms of alpha and beta diversity. We found a significant difference in the relative abundance of Campylobacter, Citrobacter, Leptotrichia, Enterobacter, Hungatella, Mycolicibacterium, Phyllobacterium and Sphingomonas between patients without and with lymph node metastasis. Conclusions: There was a significant association between the relative abundance of certain microbes and overall survival prognosis. These microbes showed association with good prognosis in cholangiocarcinoma, but with poor prognosis in pancreatic adenocarcinoma, and vice versa. Our findings suggest that pancreaticobiliary tract cancer patients have an altered microbiome composition, which might be a biomarker for distinguishing malignancy.

記述言語：日本語出版者・発行元：Journal of Chromatography A

Immobilized metal ion affinity chromatography (IMAC) is useful in purification of histidine-tagged or histidine-rich proteins and peptides from a variety of hosts. However, phenolic compounds including polyphenols interfere with IMAC due to their high affinities for the transition metals immobilized on the column resins, which hampers the purification of proteins from plant-based host systems. In contrast to extensive knowledge of the mechanism of the interactions between phenolic compounds and transition metal ions in solution, an understanding of the interactions on the columns, where transition metal ions are immobilized on the resins, remains elusive. This study systematically investigated the affinity of phenolic compounds for transition metal ions by varying the number and position of phenolic hydroxyl groups (OH groups) and using different transition metals—Fe(II), Cu(II) and Ni(II)—on various IMACs, in which the columns were fabricated by equilibrating the cation-exchange column with transition metal solutions. It was found that the more OH groups the aromatic compounds have, the higher the affinity for transition metal ions; in particular, methyl gallate and pyrogallol were permanently bound to the IMAC column, which reflected coordinate bond formation with the transition metal ions. Importantly, the phenolic compounds showed no obvious affinity for the Ni(II)-IMAC column, in contrast to the Fe(II)- and Cu(II)-IMAC columns, whereas imidazole and histidine-tagged proteins showed evident binding to the Ni(II)-IMAC column. Ni(II)-IMAC should thus be especially effective in isolating histidine-tagged and histidine-rich species from phenolic compound-containing systems. These results indicate that the affinity between phenolic compounds and transition metal ions on the column is consistent with the results in solution. They also provide a comprehensive view for devising strategies to improve IMAC purification of target proteins and peptides from samples containing phenolic compounds.

記述言語：日本語出版者・発行元：International Journal of Biological Macromolecules

Solvent additives, including NaCl, arginine hydrochloride (ArgHCl), glycine and sucrose, are used to enhance protein stability or reduce protein aggregation. Here, we studied the effects of these additives on proteins using agarose native gel electrophoresis. Since these additives are used at relatively high concentration, we first confirmed that they do not interfere with the performance of the native gel electrophoresis. Agarose native gel electrophoresis showed that aggregation of bovine serum albumin (BSA) induced by heating was slightly reduced by NaCl and ArgHCl. On the contrary, glycine and sucrose had marginal effects. ArgHCl and NaCl promoted heat aggregation of monoclonal antibody (mAb), while glycine and sucrose stabilized the native mAb. Arginine methyl ester inhibited heat aggregation of lysozyme and, to a much lesser extent, BSA. These results show that agarose native gel electrophoresis can be used to analyze the effects of solvent additives on proteins subjected to heat stresses. SYPRO Orange that stains only unfolded proteins confirmed unfolded structures of soluble aggregates.

Halophilic salilysin is first synthesized as a pro-form, which has been shown autolysis activity to process pro-region (55 amino acids long) three times to form intermediate 1 (I1), intermediate 2 (I2) and final mature (M) salilysin. The autolysis of I1- to M-form salilysin in vitro was significantly accelerated with increasing NaCl concentration up to 4 M. Strong salting-out salts, (NH4)2SO4, Na2SO4 and MgSO4, were more effective, suggesting that autolysis is enhanced by inter-molecular association or structure compaction or both. However, MgCl2, a salting-in salt, was also effective, suggesting that other mechanisms, such as charge shielding and ionic binding to this halophilic protein, operated. Autolytic cleavage at site 3 resulted in mixed formation of correctly and incorrectly processed mature forms in the absence of salt, indicating that salt affected the accuracy of autolytic cleavage reaction. Far UV circular dichroism (CD) measurements indicated that E167A pro-salilysin showed an identical CD spectrum to the wild-type mature salilysin, suggesting pro-form has a proper fold for proteolytic activity. Thermal scanning indicated that E167A pro-salilysin was more heat-stable by ~ 10 °C than mature form. The CD spectra, thermal stability and modeling structure of salilysin clearly suggested that pro-salilysin is folded to the same structure as native form and is functional for autolysis.

Soluble expression of halophilic starch-binding domain （SBD1） from Kocuria α-amylase was low due to its instability in recombinant host Escherichia coli cells. Here, the stable SBD1 protein was expressed efficiently with an aggregation-prone peptide tag in insoluble E. coli inclusion bodies （IBs）. Insoluble SBD1 protein with the tag, thus obtained, was easily solubilized with 8 M urea and refolded into an active form by simple urea dilution. The yield of active SBD1 with the tag after the solubilization / dilution method was 15 ～ 30 times higher than that of direct expression of SBD1 in soluble fraction.

Bradyrhizobium elkanii BLY3-8 does not form nodules on the roots of Rj3-genotype soybean (cultivar D-51). This is a cultivar-specific nodulation restriction. The genes A6X20_40975 and A6X20_41030 in strain BLY3-8 were predicted to encode the transcriptional activator and apparatus of the type III secretion system (T3SS) (the proteins TtsI and RhcJ), respectively. Mutants disrupted in these genes overcame the nodulation restriction. These results suggest that an effector injected via T3SS into Rj3-genotype soybean is involved in nodulation restriction by Rj3-genotype soybean.

出版者・発行元：日本海水学会

A His-Asp repeat peptide sequence was identified in a His-rich metal binding protein （HP） produced by a halophilic marine bacterium, Chromohalobacter salexigens DSM 3043T. A synthetic peptide, PepB20, containing 8 His-Asp repeats showed binding to an Ni-loaded metal-chelating column and elution around 150-200 mM imidazole in the presence of both low （0.15 M） and high （1.5 M） concentrations of NaCl. Addition of Ni or Zn ions at 0.1 to 1 mM resulted in changes in secondary structure of PepB20, leading to metal-induced insoluble aggregation at 1 mM. PepB20 showed different circular dichroism （CD） profiles induced by the binding of Ni or Zn ions, suggesting a formation of different secondary structures by these metal ions. We described metal binding properties and consequent structure changes of PepB20 examined by CD measurements and discuss the possible physiological importance of the His-rich metal binding insertion sequence found in HP.

好塩性海洋細菌Chromohalobacter salexigens由来ヒスチジン高含有金属結合タンパク質（HP）は，Treponema pallidum由来のTroAなどの良く研究されている他の金属結合タンパク質のアミノ酸配列と比較した場合，46アミノ酸残基からなるユニークな挿入配列（多くのヒスチジン残基を含むIS46配列）を持つという特徴がある．この研究では，Zn，Cu，NiもしくはMnを含んだ緩衝液に対してHPの平衡透析を行い，HPの金属結合容量を定量した．その結果，飽和条件下で1分子のHPに最大約10分子のZn，Cu，もしくはNiイオンが結合することが分った．HPに対する金属イオンの親和性は，Zn＞Cu＞Ni＞Mnの順であった．さらに，HPを利用した塩環境下での重金属回収の可能性を試した．His-tagを付与したHP（His-tagged HP）を固定化したSepharoseカラムを作成し，金属結合量を定量したところ1分子のHis-tagged HPあたり約9.5個のNiイオンが結合した．これは塩環境下における重金属の吸着・回収にHPが利用できる可能性を示したものと考えられる．

We cloned a gene, Csal-0188, from genomic DNA of Chromohalobacter salexigens DSM 3043T. This gene was annotated to encode Zn-binding protein（ZP）, which showed high homology with the His-rich metal binding protein（HP）we reported. His-tag-ZP was successfully expressed in Escherichia coli and purified. ZP was constructed with a thrombin digestion site so that His-tag could be removed. ZP and chemically synthesized oligo-peptides from the His-rich insertion sequence of ZP showed several metal binding activities. This His-rich peptide was found to bind to Ni column in the presence of 8 M urea, showing clear binding under denaturation conditions, like conventional His-tag.

We examined the effects of several detergents on the stability of halophilic Nesterenkonia halobia α-amylase（NhAmy）. NhAmy was purified to homogeneity from the culture supernatant by simple one-step dextrin affinity column chromatography. The purified enzyme was found to be highly resistant to several detergents, including sodium dodecyl sulfate, which is one of the strongest protein denaturants.
