Mutant porin proteins

In order for beta-lactam antibiotics to inhibit bacterial growth, they must pass through the bacterial cell wall using pore-forming porins. Resistance to beta-lactamases can develop via mutations in these porin proteins that no longer allow beta-lactam antibiotics to penetrate the cell wall.
