Polypeptide, DNA, Microorganism, and Process for Producing L-Arginine, L-Ornitine or L-Citrulline. It is intended to provide a polypeptide having (i) an amino acid sequence derived from the amino acid sequence represented by SEQ ID NO: 1 by substituting one or more amino acids at the amino acid sequences of positions 20 and 38 from the N terminus, or ( (ii) an amino acid sequence derived from the amino acid sequence represented by SEQ ID NO: 1 by substituting one or more amino acids in the amino acid sequences of positions 20 and 38 from the N terminus and deletion, substitution or addition of one or more amino acids. in the amino acid sequence of positions 1 to 19 or positions 39 to 294, and having an N-acetylglutamate kinase activity. |
