Thiamine monophosphate synthase (TMP) (EC:2.5.1.3) catalyses the substitution of the pyrophosphate of 2-methyl-4-amino-5- hydroxymethylpyrimidine pyrophosphate by 4-methyl-5- (beta-hydroxyethyl)thiazole phosphate to yield thiamine phosphate [1]. This Pfam family also includes the regulatory protein TENI (Swiss:P25053), a protein from Bacillus subtilis that regulates the production of several extracellular enzymes by reducing alkaline protease production [2]. While TenI shows high sequence similarity with thiamin phosphate synthase, the purified protein has no thiamin phosphate synthase activity. Instead, it is a thiazole tautomerase [3].	Domain
