Identification
HMDB Protein ID HMDBP00423
Secondary Accession Numbers
  • 5660
  • HMDBP04471
Name Nicotinamide N-methyltransferase
Synonyms Not Available
Gene Name NNMT
Protein Type Unknown
Biological Properties
General Function Involved in methyltransferase activity
Specific Function Catalyzes the N-methylation of nicotinamide and other pyridines to form pyridinium ions. This activity is important for biotransformation of many drugs and xenobiotic compounds.
