Protein

(S)-2-haloacid dehalogenase 4A

Gene

hdl IVa

Organism
Burkholderia cepacia (Pseudomonas cepacia)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalyzes the hydrolytic dehalogenation of small (S)-2-haloalkanoic acids to yield the corresponding (R)-2-hydroxyalkanoic acids. Acts on acids of short chain lengths, C2 to C4, with inversion of configuration at C-3.

Catalytic activityi

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