Translations:Thiamine/30/en

The biosynthetic pathways differ among organisms. In E. coli and other enterobacteriaceae, ThMP is phosphorylated to the cofactor TPP by a thiamine-phosphate kinase (ThMP + ATP → TPP + ADP). In most bacteria and in eukaryotes, ThMP is hydrolyzed to thiamine and then pyrophosphorylated to TPP by thiamine diphosphokinase (thiamine + ATP → TPP + AMP).
