Chain A,B (BLAC_BACLI | P00808)

molecular function
	GO:0008800	beta-lactamase activity	Catalysis of the reaction: a beta-lactam + H2O = a substituted beta-amino acid.
	GO:0016787	hydrolase activity	Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
biological process
	GO:0030655	beta-lactam antibiotic catabolic process	The chemical reactions and pathways resulting in the breakdown of a beta-lactam antibiotic, any member of a class of natural or semisynthetic antibiotics whose characteristic feature is a strained, four-membered beta-lactam ring. They include the penicillins and many of the cephalosporins.
	GO:0046677	response to antibiotic	Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an antibiotic stimulus. An antibiotic is a chemical substance produced by a microorganism which has the capacity to inhibit the growth of or to kill other microorganisms.
cellular component
	GO:0016020	membrane	A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
	GO:0005886	plasma membrane	The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
