Updated annotation (from data): RND efflux system, membrane fusion component BipC Rationale: Specifically important in stress Fusidic acid sodium salt; stress Chlorpromazine hydrochloride; and perhaps thioridazine. This protein belongs to the hlyD/MFP family of membrane fusion proteins. It is unclear if this system is an efflux pump for hydrophobic compounds, as suggested by many of its phenotypes, or an efflux pump for magnesium (PMC11078008), which apparently reduces biofilm formation and might alter susceptibility to those compounds. Original annotation: AcrA/AcrE family multidrug resistance protein (NCBI ptt file) Type 1: Protein-coding gene Located on scaffold 241, - strand, nucleotides 4,299,953 to 4,301,128 See nucleotide sequence around BT3339 or for all of scaffold 241
