Updated annotation (from data): RND efflux system, inner membrane component BipB Rationale: Specifically important in stress Fusidic acid sodium salt; stress Chlorpromazine hydrochloride; stress Thioridazine hydrochloride; stress Cefoxitin sodium salt. This protein belongs to the RND family of inner membrane transporters. 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: AcrB/AcrD family multidrug resistance protein (NCBI ptt file) Type 1: Protein-coding gene Located on scaffold 241, - strand, nucleotides 4,296,721 to 4,299,936 See nucleotide sequence around BT3338 or for all of scaffold 241
