Isoflavonoids and the related synthesis enzyme, chalcone isomerase 1 (CHI1), are unique in the Leguminosae, with diverse biological functions. Among the Leguminosae, the soybean is an important oil, protein crop, and model plant. In this study, we aimed to detect the generation pattern of Leguminosae CHI1. Genome-wide sequence analysis of CHI in 3 Leguminosae and 3 other closely related model p...

نتایج : با استفاده از روش های مورفولوژیکی 18 جدایه از قارچ متاریزیوم جداسازی شد. این جدایه ها برای مراحل بعدی تحقیق در محیط pda کشت داده و نگهداری شدند. پس از بررسی نتایج pcr مشخص شد که تمامی سویه های بومی دارای این سه ژن اصلی می باشند.اما تعدادی از سویه ها مخصوصا m4 قدرت بیماریزایی بالاتری نسبت به بقیه سویه ها داشتند به نظر می رسد که بیان موثر این ژن ها دراین سویه ها باعث ایجاد قدرت بیماریزایی...

A thermostable Chitinase Chi1 from Myceliophthora thermophila C1 was homologously produced and characterized. Chitinase Chi1 shows high thermostability at 40 °C (>140 h 90% activity), 50 °C (>168 h 90% activity), and 55 °C (half-life 48 h). Chitinase Chi1 has broad substrate specificity and converts chitin, chitosan, modified chitosan, and chitin oligosaccharides. The activity of Chitinase Chi1...

Chitinase Chi1 of Aeromonas caviae CB101 possesses chitin binding sites at both its N and C termini. Four putative exposed residues aligned in a line on the surface of the N-terminal domains of Chi1 were found to contribute to the enzyme-chitin binding and hydrolysis via site-directed mutagenesis. Also, it was found that Chi1 requires the cooperation of the N- and C-terminal domains to bind ful...

Leguminous plants produce 5-deoxyflavonoids and 5-deoxyisoflavonoids that play essential roles in legume-microbe interactions. Together with chalcone polyketide reductase and cytochrome P450 2-hydroxyisoflavanone synthase, the chalcone isomerase (CHI) of leguminous plants is fundamental in the construction of these ecophysiologically active flavonoids. Although CHIs of nonleguminous plants isom...

The ab initio folding problem can be divided into two sequential tasks of approximately equal computational complexity: the generation of native-like backbone folds and the positioning of side chains upon these backbones. The prediction of side-chain conformation in this context is challenging, because at best only the near-native global fold of the protein is known. To test the effect of displ...

We demonstrate constraint of peptide backbone and side-chain conformation with 3D (1)H-(15)N-(13)C-(1)H dipolar chemical shift, magic-angle spinning NMR experiments. In these experiments, polarization is transferred from (15)N[i] by ramped SPECIFIC cross polarization to the (13)C(alpha)[i], (13)C(beta)[i], and (13)C(alpha)[i - 1] resonances and evolves coherently under the correlated (1)H-(15)N...

The integral membrane protein M2 of influenza A virus assembles as a tetrameric bundle to form a proton-conducting channel that is activated by low pH. The side chain of His37 in the transmembrane alpha-helix is known to play an important role in the pH activation of the proton channel. It has also been suggested that Trp41, which is located in an adjacent turn of the helix, forms part of the g...
