Title:
ATP-PRT VARIANT WITH REDUCED FEEDBACK INHIBITION BY HISTIDINE, AND HISTIDINE-PRODUCING STRAIN EXPRESSING SAME
Document Type and Number:
WIPO Patent Application WO/2022/145586
Kind Code:
A1
Abstract:
The present invention relates to an E. coli hisG-derived ATP-phosphoribosyltransferase variant with reduced feedback inhibition by histidine, and a strain expressing same, the present invention maintaining activity even in a high concentration of histidine and thus enabling increased histidine production.
