benK encodes a hydrophobic permease-like protein involved in benzoate degradation by Acinetobacter sp. strain ADP1

J Bacteriol. 1997 Sep;179(18):5943-6. doi: 10.1128/jb.179.18.5943-5946.1997.


The chromosomal benK gene was identified within a supraoperonic gene cluster involved in benzoate degradation by Acinetobacter sp. strain ADP1, and benK was expressed in response to a benzoate metabolite, cis,cis-muconate. The disruption of benK reduced benzoate uptake and impaired the use of benzoate or benzaldehyde as the carbon source. BenK was homologous to several aromatic compound transporters.
