RESUMO
Mutants of Escherichia coli K-12 lacking major outer membrane proteins were obtained by selecting for resistance to the beta-lactam cefoxitin. Three classes of resistant strains were found: mutants in ompB, a regulatory locus for proteins OmpF and OmpC; mutants in ompF; and one mutant in tpo. The OmpF and OmpC proteins facilitate penetration of beta-lactams through the outer membrane.
