Dissection of the bridging pattern of bovicin HJ50, a lantibiotic containing a characteristic disulfide bridge.
Bovicin HJ50, a lantibiotic produced by Streptococcus bovis HJ50, is featured by the presence of a disulfide bridge. This study described a simplified in vitro synthetic strategy for producing bovicin HJ50 totally based on Escherichia coli expression system. In this strategy termed as Semi-in vitro biosynthesis (SIVB), prepeptide BovA and modification enzyme BovM were co-expressed to generate p...
متن کاملDBDB : a Disulfide Bridge DataBase for the predictive analysis of cysteine residues involved in disulfide bridges
We present a database of structured, verified and useful information about cysteine residues involved in disulfide bridges. The database has been filled with proteins of a subset of the PDB database called select 25. A rough analysis of the proteins contained in the database shows that it is possible to identify cysteine residues which are involved or not in a disulfide bond from the amino acid...
متن کاملInterchain and intrachain disulfide bridges of a human immunoglobulin M: detection of a unique fragment.
Studies of the amino acid sequences around half-cystine residues in an immunoglobulin M have revealed an unexpectedly high number. At least 14 different sequences were found in the mu chain (V(HIII) subclass). Four of these were involved in interchain disulfide bridges and at least 10 in intrachain bridges. Five came from the kappa chain (kappa(III) subclass, Inv b). Several others, although ha...
متن کاملMolecular Characterization of a Three-disulfide Bridges Beta-like Neurotoxin from Androctonus crassicauda Scorpion Venom
Scorpion venom is the richest source of peptide toxins with high levels of specific interactions with different ion-channel membrane proteins. The present study involved the amplification and sequencing of a 310-bp cDNA fragment encoding a beta-like neurotoxin active on sodium ion-channel from the venom glands of scorpion Androctonus crassicauda belonging to the Buthidae family using r...
متن کاملtransference of imagery: a comparative formalistic study of shakespeares hamlet and its two persian translations
هدف از این تحقیق بررسی انتقال صور خیال هملت در دو ترجمه ی فارسی آن از نظر فرمالیستی بود. برای بدست آوردن داده-های مورد نیاز، 130 نمونه استعاره، مجاز، ایهام، کنایه و پارادوکس در متن اصلی مشخص شده و سپس بر اساس مدل نیومارک (1998) برای ترجمه ی استعاره یا بطور کلی زبان مجاز با معادل های فارسی شان مقایسه گردیدند. این تحقیق بر آن بود تا روش های استفاده شده برای ترجمه هر کدام از انواع زبان مجاز ذکر شد...
