Abstract
The present disclosure relates to a novel acetohydroxy acid synthase, a microorganism comprising the same, or a method for producing an L-branched-chain amino acid using the same.
Claims8
A polynucleotide encoding an acetohydroxy acid synthase variant, wherein, in the acetohydroxy acid synthase large subunit (acetolactate synthase large subunit;
- ilvB protein) of the amino acid sequence of SEQ ID NO:1, the 503rd amino acid (tryptophan) from the N-terminal is substituted with glutamine, asparagine, or leucine.
