HALOALKANE DEHALOGENASE FROM A RHODOCOCCUS SPECIES
OverviewOverview
The hydrolytic haloalkane dehalogenases are promising bioremediation and, biocatalytic agents. Two general classes of dehalogenases have been, reported from Xanthobacter and Rhodococcus. While these enzymes share 30%, amino acid sequence identity, they have significantly different substrate, specificities and halide-binding properties. We report the 1.5 A, resolution crystal structure of the Rhodococcus dehalogenase at pH 5.5, pH, 7.0, and pH 5.5 in the presence of NaI. The Rhodococcus and Xanthobacter, enzymes have significant structural homology in the alpha/beta hydrolase, core, but differ considerably in the cap domain. Consistent with its broad, specificity for primary, secondary, and cyclic haloalkanes, the, Rhodococcus enzyme has a substantially larger active site cavity., ... [(full description)]
