摘要

PCT No. PCT/GB93/02012 Sec. 371 Date Jul. 21, 1995 Sec. 102(e) Date Jul. 21, 1995 PCT Filed Sep. 27, 1993 PCT Pub. No. WO94/08020 PCT Pub. Date Apr. 14, 1994The nucleic acid coding for an alpha -acetolactate synthase from Lactococcus is provided, as well as vectors containing this nucleic acid and the use of these vectors for transforming microorganisms in which the production of alpha -acetolactate will be promoted, The nucleic acid comprises one or the other or both of a first segment corresponding to the ilvB gene (which encodes one subunit of alpha -acetolactate synthase of Lactococcus lactis subsp. lactis) and a second segment corresponding to the ilvN gene (which encodes a second subunit of alpha -acetolactate synthase of Lactococcus lactis subsp. lactis).
