the new pbp from all strains that have been examined has an identical mobility on sds gel electrophoresis and is the only pbp still present in an uncomplexed state with beta-lactams ( and therefore the only functional pbp when these strains are grown in media containing concentrations of beta-lactam antibiotics sufficient to kill sensitive strains .
