Identification
HMDB Protein ID HMDBP12355
Secondary Accession Numbers None
Name Aminopyrimidine aminohydrolase
Synonyms Not Available
Gene Name TENA
Protein Type Unknown
Biological Properties
General Function Not Available
Specific Function Catalyzes an amino-pyrimidine hydrolysis reaction at the C5' of the pyrimidine moiety of thiamine compounds to give a hydroxymethylpyrimidine (HMP). Displays low activity on 4-amino-5-aminomethyl-2-methylpyrimidine as substrate, indicating that the enzyme may act on a different HMP precursor that may derive from the human stomach food assumption or processing. Is probably involved in thiamine biosynthesis. Does not display thiaminase II activity, as it is unable to hydrolyze thiamine.
