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.
