Biology:(R)-2-haloacid dehalogenase
From HandWiki
Short description: Class of enzymes
In enzymology, a (R)-2-haloacid dehalogenase (EC 3.8.1.9), DL-2-haloacid halidohydrolase (inversion of configuration), DL-DEXi, (R,S)-2-haloacid dehalogenase (configuration-inverting)) is an enzyme that catalyzes the chemical reaction
- (R)-2-haloacid + H2O [math]\displaystyle{ \rightleftharpoons }[/math] (S)-2-hydroxyacid + halide
Thus, the two substrates of this enzyme are (R)-2-haloacid and H2O, whereas its two products are (S)-2-hydroxyacid and halide.
This enzyme belongs to the family of hydrolases, specifically those acting on halide bonds in carbon-halide compounds. The systematic name of this enzyme class is (R)-2-haloacid halidohydrolase. Other names in common use include 2-haloalkanoic acid dehalogenase[ambiguous], 2-haloalkanoid acid halidohydrolase[ambiguous], D-2-haloacid dehalogenase, and D-DEX.
