Reaction: ATP + H2O + polar amino acidout = ADP + phosphate + polar amino acidin
Other name(s): histidine permease
Systematic name: ATP phosphohydrolase (polar-amino-acid-importing)
Comments: ABC-type (ATP-binding cassette-type) ATPase, characterised by the presence of two similar ATP-binding domains. Does not undergo phosphorylation during the transport process. Comprises bacterial enzymes that import His, Arg, Lys, Glu, Gln, Asp, ornithine, octopine and nopaline.
