Abstract excerpt
l-Histidine is an essential proteinogenic amino acid in food with extensive applications in the pharmaceutical field. Herein, we constructed a Corynebacterium glutamicum recombinant strain for efficient biosynthesis of l-histidine. First, to alleviate the l-histidine feedback inhibition, the ATP phosphoribosyltransferase mutant HisGT235P-Y56M was constructed based on molecular docking and high-throughput...
