UniProtKB - P52094 (HISQ_ECOLI)
Protein
Histidine transport system permease protein HisQ
Gene
hisQ
Organism
Escherichia coli (strain K12)
Status
Functioni
Part of the histidine permease ABC transporter. Also part of a lysine/arginine/ornithine transporter. Probably responsible for the translocation of the substrate across the membrane. Required to relay the ATPase-inducing signal from the solute-binding protein to HisP (By similarity).By similarity
