Liver preparations from Syrian golden hamsters catalyze the metabolism of the pancreatic carcinogen N-nitroso-2,6-dimethylmorpholine largely to N-nitroso(2-hydroxypropyl)(2-oxopropyl)amine (HPOP). This reaction is catalyzed by a mixed-function oxidase in the presence of reduced nicotinamide adenine dinucleotide phosphate and oxygen at a rate of 3.8 nmol/min/mg of protein, and it is inhibited by...
