Analysis of Staphylococcus aureus genes encoding penicillin-binding protein 4 and an ABC-type transporter

Gene. 1995 Dec 29;167(1-2):111-3. doi: 10.1016/0378-1119(96)82965-9.

Abstract

A region of the Staphylococcus aureus chromosome has been isolated that contains the gene encoding penicillin-binding protein 4 (PBP4), as well as abcA, a gene that encodes a protein with strong sequence similarity to the ABC transporter family of proteins. A disruption in abcA by Campbell-type integration results in cells that display an increased resistance to methicillin and cefoxitin, two antibiotics known to interact with low-molecular-weight PBPs. Based on these observations, a potential regulatory link between these two genes is discussed.
