Protein

(S)-2-haloacid dehalogenase 4A

Gene

hdl IVa

Organism
Burkholderia cepacia (Pseudomonas cepacia)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-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.

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
