Expression of beta-lactamase neutralizes ampicillin. When this enzyme | Expression of [[β-lactamase]] neutralizes ampicillin. When this enzyme is expressed on a high-copy number plasmid there is significant diffusion into the extracellular medium. As a result non-resistant satellite colonies may form around larger resistant colonies. | ||
