Process for the preparation of L-amino acids by fermentation and nucleotide sequences coding for the accDA gene

摘要

Cloned Corynebacterium glutamicum DNA (I), replicable in coryneform microorganisms coding for an accDA gene having a fully defined 2123 bp sequence (given in the specification(), is new. Independent claims are also included for the following: (1) a polypeptide derived from (I) having a fully defined 491 aa sequence (given in the specification); (2) coryneform microorganisms transformed with one or more copies of (I); (3) the shuttle vector pZ1accDA contained in Corynebacterium glutamicum DSM 12785; and (4) a process for producing L-amino acids, comprising culturing a coryneform bacterium that overexpresses the accDA gene.
