Gene: pth, PA4672 (PSEAE) Activity: Aminoacyl-tRNA hydrolase, with EC number 3.1.1.29 Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function [PTH_PSEAE] The natural substrate for this enzyme may be peptidyl-tRNAs which drop off the ribosome during protein synthesis (By similarity). Publication Abstract from PubMed The peptidyl-tRNA hydrolase enzyme from the pathogenic bacterium Pseudomonas aeruginosa (Pth; EC 3.1.1.29) has been cloned, expressed in Escherichia coli and crystallized for X-ray structural analysis. Suitable crystals were grown using the sitting-drop vapour-diffusion method after one week of incubation against a reservoir solution consisting of 20% polyethylene glycol 4000, 100 mM Tris pH 7.5, 10%(v/v) isopropyl alcohol. The crystals were used to obtain the three-dimensional structure of the native protein at 1.77 A resolution. The structure was determined by molecular replacement of the crystallographic data processed in space group P6(1)22 with unit-cell parameters a = b = 63.62, c = 155.20 A, alpha = beta = 90, gamma = 120 degrees . The asymmetric unit of the crystallographic lattice was composed of a single copy of the enzyme molecule with a 43% solvent fraction, corresponding to a Matthews coefficient of 2.43 A(3) Da(-1). The crystallographic structure reported here will serve as the foundation for future structure-guided efforts towards the development of novel small-molecule inhibitors specific to bacterial Pths.
