The enzyme characterised from Escherichia coli converts thiamine to thiamine monophosphate by transferring a phosphate group from the cofactor, adenosine triphosphate (ATP), which is converted to adenosine diphosphate (ADP).[1]
This enzyme is a transferase, specifically one transferring phosphorus-containing groups (phosphotransferases) with an alcohol group as acceptor. The systematic name of this enzyme class is ATP:thiamine phosphotransferase. Other names in common use include thiamin kinase (phosphorylating), thiamin phosphokinase, ATP:thiamin phosphotransferase, and thiamin kinase. This enzyme participates in thiamine metabolism.[2]
