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 Escherichia coli (strain K12) heteromer 1 Cluster1 ecocyc::HISP-MONOMER b2306 lysine/arginine/ornithine ABC transporter / histidine ABC transporter, ATP binding subunit (EC 7.4.2.1) Escherichia coli K-12 substr.
