'''STRUCTURE OF MUCONATE LACTONIZING ENZYME AT 1.85 ANGSTROMS RESOLUTION'''<br />


==Overview==
==STRUCTURE OF MUCONATE LACTONIZING ENZYME AT 1.85 ANGSTROMS RESOLUTION==
We report here the refined X-ray crystal structure of muconate lactonizing, enzyme (MLE) from Pseudomonas putida PRS2000 at a resolution of 1.85 A, with an R-factor of 16.8%. An enzyme from the beta-ketoadipate pathway, MLE catalyses the conversion of cis,cis-muconate to muconolactone. It is a, homo-octamer, one monomer consisting of 373 amino acid residues. MLE has, two large domains and a C-terminal subdomain: an alpha + beta domain, an, alpha beta-barrel domain and a C-terminal meandering subdomain. The alpha, beta-barrel domain is highly irregular. Its structure is (beta/alpha)7, beta, with the structural role of the last alpha-helix being replaced by, both the C-terminal subdomain and part of the N-terminal domain. The, fifth, seventh and eighth barrel strands are unusual because ... [[http://ispc.weizmann.ac.il/pmbin/getpm?7500361 (full description)]]
