Enzyme Information

3.5.99.2
Aminopyrimidine aminohydrolase.
based on mapping to UniProt Q6GEY1
(1) 4-amino-5-aminomethyl-2-methylpyrimidine + H(2)O = 4-amino-5- hydroxymethyl-2-methylpyrimidine + ammonia. (2) Thiamine + H(2)O = 4-amino-5-hydroxymethyl-2-methylpyrimidine + 5-(2-hydroxyethyl)-4-methylthiazole.
-!- Previously known as thiaminase II, this enzyme is involved in the regeneration of the thiamine pyrimidine from degraded products, rather than in thiamine degradation, and participates in thiamine salvage pathways.
