[https://www.uniprot.org/uniprot/DHAA_RHORH DHAA_RHORH] Catalyzes hydrolytic cleavage of carbon-halogen bonds in halogenated aliphatic compounds, leading to the formation of the corresponding primary alcohols, halide ions and protons. Expresses halogenase activity against 1-chloroalkanes of chain length C3 to C10, and also shows a very weak activity with 1,2-dichloroethane.

== Publication Abstract from PubMed ==
+
-
We emphasize the importance of dynamics and hydration for enzymatic catalysis and protein design by transplanting the active site from a haloalkane dehalogenase with high enantioselectivity to nonselective dehalogenase. Protein crystallography confirms that the active site geometry of the redesigned dehalogenase matches that of the target, but its enantioselectivity remains low. Time-dependent fluorescence shifts and computer simulations revealed that dynamics and hydration at the tunnel mouth differ substantially between the redesigned and target dehalogenase.
