The invention relates to a method for improving the yield of arginine by the mutation of Corynebacterium crenatum N-acetyl glutamic acid kinase. L-arginine is one of semi-essential basic amino acids for a human body, and has various particular physiology and pharmacology functions. High-yield arginine mutant strain C. crenatum SYPA5-5 is compounded into the arginine through a circulating way, and N-acetyl glutamic acid kinase (NAGK) is a key enzyme in the compounding way and is subject to the feedback inhibition of the product arginine. By using an overlapping PCR (Polymerase Chain Reaction) technique, a GAT (glycerol phosphate acyl transferase) codon used for coding aspartic acid is used for substituting a GGA (General Gonadotropic activity) codon used for coding glycine at the site 287 in the coding NAGK albumen, and the NAGK which has high activity and arginine with obviously reduced by the feedback inhibition can be obtained after the mutation. An argBSD gene is brought into the Corynebacterium crenatum of the high-yield arginine through pJCl-tac, and the expression volume of the key enzyme is further improved. The final acid yield is increased to 36.3g/L from original 28g/L, and the yield of the L-arginine is increased by 29.7 percent.
