Protein
Haloalkane dehalogenase
Gene
dhlA
Organism
Xanthobacter autotrophicus
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Catalyzes hydrolytic cleavage of carbon-halogen bonds in halogenated aliphatic compounds, leading to the formation of the corresponding primary alcohols, halide ions and protons. Has a broad substrate specificity, which includes terminally mono- and di- chlorinated and brominated alkanes (up to C4 only). The highest activity was found with 1,2-dichloroethane, 1,3-dichloropropane, and 1,2-dibromoethane.UniRule annotation

Catalytic activityi

1-haloalkane + H2O = a primary alcohol + halide.UniRule annotation
1,2-dichloroethane + H2O = 2-chloroethanol + hydrogen chloride.UniRule annotation

Enzyme regulationi

Inhibited by thiol reagents such as p-chloromercuribenzoate and iodoacetamide.UniRule annotation

pH dependencei

Optimum pH is 8.2.UniRule annotation

Temperature dependencei

Optimum temperature is 37 degrees Celsius.
