CRYSTAL STRUCTURE OF THE N-TERMINAL DIMER DOMAIN OF E.COLI DSBC
OverviewOverview
DsbC and DsbG are periplasmic disulfide-bond isomerases, enzymes that, facilitate the folding of secreted proteins with multiple disulfide bonds, by catalyzing disulfide-bond rearrangement. Both enzymes also have in, vitro chaperone activity. The crystal structures of these molecules are, similar and both are V-shaped homodimeric modular structures. Each dimeric, molecule contains two separate C-terminal thioredoxin-fold domains, joined, by hinged helical "stalks" to a single N-terminal dimerization domain, formed from the N-terminal 67 residues of each monomer. In this work, the, crystal structures of the separate DsbC and DsbG dimerization domains have, been determined at resolutions of 2.0 and 1.9 A, respectively. The two, structures are both similar to the corresponding domains in ... [(full description)]
