Crystal Structure of the putative proline racemase from Brucella melitensis, Northeast Structural Genomics Target LR31
Structural highlights
Function[Y1586_BRUME] In vitro, catalyzes the epimerization of trans-4-hydroxy-L-proline (t4LHyp) to cis-4-hydroxy-D-proline (c4DHyp) and that of trans-3-hydroxy-L-proline (t3LHyp) to cis-3-hydroxy-D-proline (c3DHyp), albeit with very low efficiency. The physiological substrate may be different (PubMed:24980702). Displays neither proline racemase activity nor t3LHyp dehydratase activity (PubMed:17849014, PubMed:24980702).[1] [2] [3] Evolutionary Conservation Check, as determined by ConSurfDB.

Publication Abstract from PubMedStructural genomics efforts have produced structural information, either directly or by modeling, for thousands of proteins over the past few years. While many of these proteins have known functions, a large percentage of them have not been characterized at the functional level. The structural information has provided valuable functional insights on some of these proteins, through careful structural analyses, serendipity, and structure-guided functional screening. Some of the success stories based on structures solved at the Northeast Structural Genomics Consortium (NESG) are reported here. These include a novel methyl salicylate esterase with important role in plant innate immunity, a novel RNA methyltransferase (H. influenzae yggJ (HI0303)), a novel spermidine/spermine N-acetyltransferase (B. subtilis PaiA), a novel methyltransferase or AdoMet binding protein (A. fulgidus AF_0241), an ATP:cob(I)alamin adenosyltransferase (B. subtilis YvqK), a novel carboxysome pore (E. coli EutN), a proline racemase homolog with a disrupted active site (B. melitensis BME11586), an FMN-dependent enzyme (S. pneumoniae SP_1951), and a 12-stranded beta-barrel with a novel fold (V. parahaemolyticus VPA1032).
