N(omega)-phosphohypotaurocyamine

The enzyme characterised from sipunculid worms converts hypotaurocyamine to N-phosphohypotaurocyamine by transferring a phosphate group from the cofactor, adenosine triphosphate (ATP), which is converted to adenosine diphosphate (ADP).[1][2] There is evidence that the gene encoding this enzyme evolved from one coding for arginine kinase.[3][4] The reaction is reversible for the phosphagen product.[5]

This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with a nitrogenous group as acceptor. The systematic name of this enzyme class is ATP:hypotaurocyamine N-phosphotransferase.[6]
