Comments We divided the haloalkane dehalogenase family into two subfamilies. Each of which contains a catalytic triad with a different topological arrangement and different amino acids. Moreover, subfamily 1 seems to have a preference for short-chain haloalkanes as substrates, whereas subfamily 2 seems to prefer long-chains.
