Abstract :

ABSTRACT A method for the detection of haloalkane conversion to the corresponding alcohols by haloalkane dehalogenases is described It is based on a multistage enzyme reaction which allows for the analysis of alkyl halides in buffered systems Irreversible hydrolytic dehalogenation catalyzed by haloalkane dehalogenase DhaA from Rhodococcus erythropolis transfers an alkyl halide into a corresponding alcohol that is further oxidized by alcohol oxidase AOX from Pichia pastoris yielding a respective aldehyde and hydrogen peroxide easily detectable via the horseradish peroxidase catalyzed oxidation of chromogenic molecules Due to its high sensitivity 0.025 mM 0.43 ppm for 1,3-dibromopropane low expenditure and the ability of handling a large number of samples in parallel this method is an attractive alternative to existing procedures for the monitoring of both haloalkanes and dehalogenases.
