PROLINE IMINOPEPTIDASE FROM XANTHOMONAS CAMPESTRIS PV. CITRI
Overview
The proline iminopeptidase from Xanthomonas campestris pv. citri is a, serine peptidase that catalyses the removal of N-terminal proline residues, from peptides with high specificity. We have solved its three-dimensional, structure by multiple isomorphous replacement and refined it to a, crystallographic R-factor of 19.2% using X-ray data to 2.7 A resolution., The protein is folded into two contiguous domains. The larger domain shows, the general topology of the alpha/beta hydrolase fold, with a central, eight-stranded beta-sheet flanked by two helices and the 11 N-terminal, residues on one side, and by four helices on the other side. The smaller, domain is placed on top of the larger domain and essentially consists of, six helices. The active site, located at the end of a deep pocket at ... [(full description)]
