Metabolite Identification
Common Name4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanone
Description4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) is a potent tobacco-specific nitrosamine in animals. It has been suggested to play a role in human tobacco-related cancers. In a reconstituted system in E. coli, P450 1A2 catalyzed the formation of keto alcohol and 4-oxo-1-(3-pyridyl)-1-butanone (keto aldehyde) from NNK, with the keto alcohol being the major metabolite. Phenethyl isothiocyanate (PEITC) may be an effective inhibitor of the carcinogenicity or toxicity of chemicals that are activated by P450 1A2. (PMID: 8625495 ).

Enzymes

General function:
Involved in oxidoreductase activity
Specific function:
NADPH-dependent reductase with broad substrate specificity. Catalyzes the reduction of a wide variety of carbonyl compounds including quinones, prostaglandins, menadione, plus various xenobiotics. Catalyzes the reduction of the antitumor anthracyclines doxorubicin and daunorubicin to the cardiotoxic compounds doxorubicinol and daunorubicinol. Can convert prostaglandin E2 to prostaglandin F2-alpha. Can bind glutathione, which explains its higher affinity for glutathione-conjugated substrates. Catalyzes the reduction of S-nitrosoglutathione.
