This is the central, beta-barrel, domain of the metallo-carboxypeptidase that maintains helical cell-shape in Helicobacter. It shows a novel fold. It has a highly positively charged surface which contributes to a high overall isoelectric point. A calcium-binding channel is formed from residues in the C-terminal Ig-like domain in conjunction with some of the long side-chains of residues from strands beta-14 and beta-18 of this domain [1].
This is the peptidase domain of a D,L-carboxypeptidase. The active site residues are Arg86, Glu222 and the metal ligands, in the peptidase domain, are Gln46, Glu49 and His128 in UniProtKB:O25708. The protein binds many zinc ions and a calcium ion a ...
This is the peptidase domain of a D,L-carboxypeptidase. The active site residues are Arg86, Glu222 and the metal ligands, in the peptidase domain, are Gln46, Glu49 and His128 in UniProtKB:O25708. The protein binds many zinc ions and a calcium ion and there are other metal binding sites. The catalytic activity is the release of m-Dpm from the peptide muramyl-Ala-gamma-D-Glu-m-Dpm; this is probably the precursor of the cell wall cross-linking peptide [1].
C-terminal immunoglobulin-like domain of helical cell shape-determining peptidoglycan hydrolases, a metallo-carboxypeptidase. The structural elements of this domain form a Ca2+ binding-channel, the Ca2+ being co-ordinated by six ligand-atoms [1].
