:ATP + D-glyceraldehyde

\rightleftharpoons

ADP + D-glyceraldehyde 3-phosphate Thus, the two substrates of this enzyme are ATP and D-glyceraldehyde, whereas its two products are ADP and D-glyceraldehyde 3-phosphate. This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups ( phosphotransferases) with an alcohol group as acceptor. The
