Abstract:
Provided is a process for the preparation of L-methionine in an enzymatic reaction utilizing dimethyl disulfide (DMDS) a precursor of L-methionine, and an organic reducing compound. In the process, methyl mercaptan can be formed by the enzymatic hydrogenolysis of the DMDS.

Claim (Index 17):
The process of  claim 16 , comprising:\n (a\u2032) preparing a mixture, comprising:\n (1) dimethyl disulfide (DMDS), \n (2) a catalytic amount of an amino acid bearing a thiol group or of a thiol-group-containing peptide, wherein the amino acid bearing a thiol group or the thiol-group-containing peptide may be in the form of the corresponding disulfide, \n (3) a catalytic amount of a reductase enzyme catalyzing the reduction reaction of the disulfide bridge of the amino acid bearing a thiol group or of the thiol-group-containing peptide, and \n (4) a catalytic amount of NADPH, \n (b\u2032) adding an organic reducing compound in a stoichiometric amount relative to the dimethyl disulfide with a catalytic amount of the dehydrogenase enzyme catalyzing the reaction for the dehydrogenation of the organic reducing compound, (c\u2032) carrying out the enzymatic reaction to form methyl mercaptan (CH 3 \u2014SH), (d\u2032) converting an L-methionine precursor with the methyl mercaptan formed in (c\u2032) to L-methionine, and (e\u2032) recovering and optionally purifying the L-methionine.
