[https://www.uniprot.org/uniprot/CEAS_STRCL CEAS_STRCL] 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.<ref>PMID:18052280</ref> <ref>PMID:19477162</ref>
