The gene adh encoding a NAD-dependent alcohol dehydrogenase from the novel strain RC3 of Sulfolobus sp. was cloned and sequenced. Both the adh gene from Sulfolobus sp. strain RC3 and the alcohol dehydrogenase gene from Sulfolobus solfataricus (DSM 1617) were expressed at a high level in Escherichia coli, and the recombinant enzymes were purified, characterized, and compared. Only a few amino acid replacements were responsible for the different kinetic and physicochemical features investigated.
克隆并测序了来自嗜硫裂片菌新菌株RC3的编码NAD依赖性乙醇脱氢酶的adh基因。嗜硫裂片菌菌株RC3的adh基因和嗜热栖热菌(DSM 1617)的乙醇脱氢酶基因均在大肠杆菌中高水平表达,对重组酶进行了纯化、表征和比较。在所研究的不同动力学和物理化学特性中,只有少数氨基酸替换起作用。
