Provided is a novel process for producing an L-amino acid using a microorganism belonging to the genus Escherichia . According to the present invention, a process for producing an L-amino acid comprising; culturing a microorganism in which an activity of the protein of any of the following [1] - [3] is increased compared with that of the parent strain in a medium, producing and accumulating the L-amino acid in the medium, and recovering the L-amino acid from the medium:
[1] a protein comprising the amino acid sequence shown in SEQ ID NO: 2
[2] a protein consisting of an amino acid sequence in which one or more amino acids are deleted, substituted or added in the amino acid sequence shown in SEQ ID NO: 2, and having YeiG activity
[3] a protein consisting of an amino acid sequence having 80% or more homology to the amino acid sequence shown in SEQ ID NO: 2, and having YeiG activity. |
