Nocardicin A
Encyclopedia
Nocardicin A is a β-lactam antibiotic
included in the monobactam subclass. It is secreted by the bacterium Nocardia

Enzyme
Enzymes are proteins that catalyze chemical reactions. In enzymatic reactions, the molecules at the beginning of the process, called substrates, are converted into different molecules, called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates...
