Aminopyrimidine aminohydrolase (EC 3.5.99.2, thiaminase, thiaminase II, tenA (gene)) is an enzyme with systematic name 4-amino-5-aminomethyl-2-methylpyrimidine aminohydrolase. It catalyses the hydrolysis of thiamine to toxopyrimidine and 4-methyl-5-thiazoleethanol, which is the first step in the salvage pathway for vitamin B1: This enzyme was previously known as thiaminase II. It also catalyses another reaction in thiamine salvage, the conversion of 4-amino-2-methyl-5-pyrimidinemethanamine to toxopyrimidine:
