    Abstract: The present invention relates to a novel epoxide hydrolase enzyme which aims to achieve a high degree of resolution towards a broader range of substrates with high enantioselectivity and yields with minimal product inhibition. The invention further relates to a new bacterial strain Achromobacter sp. MTCC 5605 isolated from a petroleum-contaminated sludge sample, capable of producing the said enzyme. It is notable that the enzyme can be used as whole bacterial cell preparation, which allows continuous hydrolysis of substrates at even higher concentration and have an advantage of being recycled. The invention further relates to a process for the hydrolysis of different aryl epoxides which are potential synthons of intermediates for the synthesis of chiral amino alcohols and bioactive compounds like beta-blockers.

    Abstract: The invention relates to a process for the preparation of an enantiomerically enriched nitrile by reacting an epihalohydrin (derivative) with Br - and CN - in the presence of an enantioselective haloalcohol dehalogenase. The process of the invention leads to enantiomerically enriched nitriles in a high yield and in a high enantiomeric excess. Preferably the haloalcohol dehalogenase used is HheC, more preferably HheC from Agrobacterium radiobacter AD1, most preferably the W249F mutant from HheC from Agrobacterium radiobacter AD1. In one preferred embodiment of the invention the epihalohydrin (derivative) is epichlorohydrin. The enantiomerically enriched nitriles obtained by the process of the invention are especially suitable as intermediates in the preparation of statins, in particular of atorvastatin or rosuvastatin.

    Abstract: A process for the production of an altered microbial enzyme, especially an aminotransferase, which displays catalytic activity towards the L-enantiomer of an amino acid which is not the normal substrate for the precursor enzyme comprises treating a microorganism with a mutagenic agent, growing the microorganism so treated on a medium containing said amino acid as the sole nitrogen source and isolating surviving microorganisms containing enzymes capable of using said amino acid as a substrate. The process involves the use of a random chemical mutagen followed by a biological selection procedure and does not require prior knowledge of the protein structure of the enzyme nor site-directed mutagenesis.
