Popis: | The adk gene from Bacillus stearothermophilus was cloned and overexpressed in Escherichia coli under the control of the lac promoter. The primary structure of B. stearothermophilus adenylate kinase exhibited 76% identity with the enzyme from Bacillus subtilis, 60% identity with the enzyme from Lactococcus lactis, and 42% identity with the enzyme from E. coli. The most striking property of the adenylate kinase from B. stearothermophilus is the presence of a structural zinc atom bound to four cysteines in a zinc finger-like fashion. The ability to coordinate zinc is predicted also for a number of other isoforms of bacterial adenylate kinases. Furthermore, the tightly bound metal ion contributes to the high thermodynamic stability of adenylate kinase from B. stearothermophilus. |
