THREE-DIMENSIONAL STRUCTURE OF THE ELASTASE OF PSEUDOMONAS AERUGINOSA AT 1.5 ANGSTROMS RESOLUTIONTHREE-DIMENSIONAL STRUCTURE OF THE ELASTASE OF PSEUDOMONAS AERUGINOSA AT 1.5 ANGSTROMS RESOLUTION
Structural highlights
FunctionELAS_PSEAE Cleaves elastin, collagen, IgG, and several complement components. Involved in the pathogenesis of P.aeruginosa infections. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedPseudomonas aeruginosa elastase (PAE) is a zinc metalloprotease with 301 amino acids. We have crystallized and solved the three-dimensional structure of PAE, using data to 1.5-A resolution, and have refined the native molecular structure to R = 0.188. The overall tertiary structure of the PAE molecule is similar to that of thermolysin, with which it shares 28% amino acid sequence identity. Nearly all of the active site residues that might potentially interact with substrates are identical in the two proteins. However, the active site cleft is significantly more "open" in PAE than in thermolysin.
