- ATP + guanidinoethyl methyl phosphate
ADP + N'-phosphoguanidinoethyl methylphosphate
Thus, the two substrates of this enzyme are ATP and guanidinoethyl methyl phosphate, whereas its two products are ADP and N'-phosphoguanidinoethyl methylphosphate.
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:guanidinoethyl-methyl-phosphate phosphotransferase.
