DESCRIPTION

Also known as CEAS_STRCL, ceaS. Involved in the biosynthesis of the beta-lactamase inhibitor, clavulanic acid. Catalyzes the thiamine diphosphate (ThDP) dependent condensation of D-glyceraldehyde-3-phosphate (D-G3P) with L-arginine to yield the beta-amino acid, N2-(2-carboxyethyl)arginine (CEA) via a beta-elimination resulting in the formation of an enol which undergoes a second elimination to generate the alpha, beta-unsaturated acryloyl-ThDP. Homotetramer; dimer of dimers.
