Enzyme Commission Summary for
Acts on acids of short chain lengths, C(2) to C(4), with inversion

Enzyme Commission Summary for
Dehalogenates both (S)- and (R)-2-haloalkanoic acids to the corresponding (R)- and (S)-hydroxyalkanoic acids, respectively, with inversion of configuration at C-2. The enzyme from Pseudomonas sp. 113 acts on 2-haloalkanoic acids whose carbon chain lengths are five or less.
