Mutation of lipoprotein processing pathway gene lspA or inhibition of LspA activity by globomycin increases MRSA resistance to β-lactam antibiotics.

Resistance to β-lactam antibiotics in methicillin-resistant Staphylococcus aureus is mediated by the mecA-encoded, β-lactam-resistant transpeptidase, penicillin-binding protein 2a (PBP2a), which is capable of crosslinking peptidoglycan in the presenc…
