阅读说明：本技术 一种重组nad合成酶及其基因和应用 (Recombinant NAD synthetase, gene and application thereof ) 是由 张章 张琦 于 2019-06-27 设计创作，主要内容包括：提供一种重组NAD合成酶及其基因和应用。该酶包含来源于流感嗜血杆菌的烟酰胺单核苷酸腺苷转移酶结构域以及来源于人类、酿酒酵母、大肠杆菌和鼠伤寒沙门氏菌中的任意一种的烟酰胺核糖激酶结构域,能够应用于工业生产中以NR和ATP为原料规模化生产NAD。(Provides a recombinant NAD synthetase, a gene and an application thereof. The enzyme comprises a nicotinamide mononucleotide adenylyltransferase structural domain derived from haemophilus influenzae and a nicotinamide ribokinase structural domain derived from any one of human beings, saccharomyces cerevisiae, escherichia coli and salmonella typhimurium, and can be applied to large-scale production of NAD by taking NR and ATP as raw materials in industrial production.)
