Ligands: F Gene: dhaA (Rhodococcus rhodochrous) Activity: Haloalkane dehalogenase, with EC number 3.8.1.5 Resources: FirstGlance, OCA, RCSB, PDBsum Function [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 Mutations targeting as few as four residues lining the access tunnel extended the half-life of an enzyme in 40 % dimethyl sulfoxide from minutes to weeks and increased its melting temperature by 190 degrees C. Protein crystallography and molecular dynamics revealed that the tunnel residue packing is a key determinant of protein stability and the active-site accessibility for cosolvent molecules (red dots).
