    30655   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. 
    46677   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. 
    8800   Beta Lactamase Activity  Catalysis of the Reaction: a Beta Lactam + H2o = a Substituted Beta Amino Acid. 
    16787   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.
