摘要：

An enzyme catalysing nitrosamine formation was isolated and purified from two denitrifying microorganisms, Pseudomonas aeruginosa and Neisseria mucosae. The soluble enzyme has a molecular weight of 66 as determined by gel filtration and SDS-polyacrylamide gel electrophoresis and a pH optimum for P. aeruginosa of 7.25. A number of microorganisms isolated from human infections have previously been found to possess nitrosating enzymes. © 1990.
