19919101-6	2009	The carboxylate attached to the beta-lactam ring of doripenem is stabilized by a salt bridge to K212 and a hydrogen bond with T213, in lieu of the interaction with an arginine side chain found in most other beta-lactamase-beta-lactam complexes (e.g., R244 in the class A member TEM-1).	carboxylate	4-15	CD248 molecule	Homo sapiens	278-283	
8605632-5	1996	The carboxylate of Asp 49 forms hydrogen bonds to four conserved, catalytic residues in the beta-lactamase, thereby mimicking the position of the penicillin G carboxylate observed in the acyl-enzyme complex of TEM-1 with substrate.	carboxylate	4-15	CD248 molecule	Homo sapiens	210-215
