What is "triokinase"

n. (context enzyme English) A transferase enzyme that catalyzes the chemical reaction ''ATP + D-glyceraldehyde $rightleftharpoons$ ADP + D-glyceraldehyde 3-phosphate''.

In enzymology, a triokinase is an enzyme that catalyzes the chemical reaction

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 systematic name of this enzyme class is ATP:D-glyceraldehyde 3-phosphotransferase. This enzyme is also called triose kinase. This enzyme participates in fructose metabolism.
