b2308 lysine/arginine/ornithine ABC transporter / histidine ABC transporter, membrane subunit HisQ (EC 7.4.2.1) from Escherichia coli K-12 substr. MG1655 (heteromeric)
HISQ_ECOLI / P52094 Histidine transport system permease protein HisQ from Escherichia coli (strain K12) (heteromeric)
TC 3.A.1.3.29 / P52094 Histidine transport system permease protein HisQ, component of Histidine/Arginine/Lysine (basic amino acid) uptake porter, HisJ/ArgT/HisP/HisM/HisQ [R, R, C, M, M, respectively] (Gilson et al. 1982). HisJ binds L-His (preferred), but 1-methyl-L-His and 3-methyl-L-His also bind, while the dipeptide carnosine binds weakly; D-histidine and the histidine degradation products, histamine, urocanic acid and imidazole do not bind. L-Arg, homo-L-Arg, and post-translationally modified methylated Arg-analogs also bind with the exception of symmetric dimethylated-L-Arg. L-Lys and L-Orn show weaker interactions with HisJ and methylated and acetylated Lys variants show poor binding.The carboxylate groups of these amino acids and their variants are essential from Escherichia coli (strain K12) (heteromeric)

HISQ_SALTY / P0A2I9 Histidine transport system permease protein HisQ from Salmonella typhimurium (strain LT2 / SGSC1412 / ATCC 700720) (heteromeric)
TC 3.A.1.3.1 / P0A2I9 Histidine transport system permease protein HisQ aka STM2353, component of Histidine/arginine/lysine/ornithine porter (Heuveling et al. 2014). In contrast to some homologous homodimeric systems, the heterodimeric histidine transporter of Salmonella enterica Typhimurium from Salmonella typhimurium (heteromeric)

TC 3.A.1.3.23 / Q9HU30 Probable permease of ABC transporter, component of Amino acid transporter, PA5152-PA5155. Probably transports numerous amino acids including lysine, arginine, histidine, D-alanine and D-valine (Johnson et al. 2008). Regulated by ArgR from Pseudomonas aeruginosa (strain ATCC 15692 / PAO1 / 1C / PRS 101 / LMG 12228) (heteromeric)
