Protein

(S)-2-haloacid dehalogenase

Gene

dhlB

Organism
Xanthobacter autotrophicus
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalyzes the hydrolytic dehalogenation of small L-2-haloalkanoic acids to yield the corresponding D-2-hydroxyalkanoic acids. Active with 2-halogenated carboxylic acids and converts only the L-isomer of 2-chloropropionic acid with inversion of configuration to produce D-lactate.

Catalytic activityi

(S)-2-haloacid + H2O = (R)-2-hydroxyacid + halide.

pH dependencei

Optimum pH is 9.5.
