glyceraldehyde-3-phosphate:L-arginine N2-(2-hydroxy-3-oxopropyl) transferase (2-carboxyethyl-forming)
D-glyceraldehyde 3-phosphate + L-arginine = N2-(2-carboxyethyl)-L-arginine + phosphate [RN:
D-glyceraldehyde 3-phosphate [CPD:
The enzyme requires thiamine diphosphate and catalyses the first step in the clavulanic-acid-biosynthesis pathway. The 2-hydroxy-3-oxo group transferred from glyceraldehyde 3-phosphate is isomerized during transfer to form the 2-carboxyethyl group.
