CRYSTAL STRUCTURE OF 3-CHLOROCATECHOL 1,2-DIOXYGENASE FROM RHODOCOCCUS OPACUS 1CP
OverviewOverview
The crystal structure of the 3-chlorocatechol 1,2-dioxygenase from the, Gram-positive bacterium Rhodococcus opacus (erythropolis) 1CP, a Fe(III), ion-containing enzyme specialized in the aerobic biodegradation of, 3-chloro- and methyl-substituted catechols, has been solved by molecular, replacement techniques using the coordinates of 4-chlorocatechol, 1,2-dioxygenase from the same organism (PDB code 1S9A) as a starting model, and refined at 1.9 A resolution (R(free) 21.9%; R-factor 17.4%). The, analysis of the structure and of the kinetic parameters for a series of, different substrates, and the comparison with the corresponding data for, the 4-chlorocatechol 1,2-dioxygenase isolated from the same bacterial, strain, provides evidence of which active site residues are responsible, for the ...
