Para-hydroxybenzoic acid efflux pump subunit AaeB/fusaric acid resistance protein (IPR006726)

Short name: PHBA_efflux_AaeB/fusaric-R

Overlapping homologous superfamilies


Family relationships


This entry represents the p-hydroxybenzoic acid efflux pump subunit AaeB (pHBA efflux pump protein B) whose substrates are p-hydroxybenzoic acid (pHBA), 6-hydroxy-2-naphthoic and 2-hydroxycinnamate. It could function as a metabolic relief valve, allowing to eliminate certain compounds when they accumulate to high levels in the cell [PMID: 15489430]. This family also includes fusaric acid resistance proteins [PMID: 1370369], which are likely to be membrane transporter proteins, and uncharacterised transporter YdhK.
