'''CRYSTAL STRUCTURE OF THE PROTEIN DISULFIDE BOND ISOMERASE, DSBC, FROM ESCHERICHIA COLI'''
===CRYSTAL STRUCTURE OF THE PROTEIN DISULFIDE BOND ISOMERASE, DSBC, FROM ESCHERICHIA COLI===




==Overview==
<!--
DsbC is one of five Escherichia coli proteins required for disulfide bond formation and is thought to function as a disulfide bond isomerase during oxidative protein folding in the periplasm. DsbC is a 2 x 23 kDa homodimer and has both protein disulfide isomerase and chaperone activity. We report the 1.9 A resolution crystal structure of oxidized DsbC where both Cys-X-X-Cys active sites form disulfide bonds. The molecule consists of separate thioredoxin-like domains joined via hinged linker helices to an N-terminal dimerization domain. The hinges allow relative movement of the active sites, and a broad uncharged cleft between them may be involved in peptide binding and DsbC foldase activities.
The line below this paragraph, {{ABSTRACT_PUBMED_10700276}}, adds the Publication Abstract to the page
(as it appears on PubMed at http://www.pubmed.gov), where 10700276 is the PubMed ID number.
