Chain A   (MECR_STAAN | P0A0B0)
molecular function
    GO:0008658    penicillin binding    Interacting selectively and non-covalently with penicillin, any antibiotic that contains the condensed beta-lactamthiazolidine ring system.
biological process
    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.
