IntEnz Enzyme Nomenclature
EC 3.6.3.21

Names

Accepted name:
polar-amino-acid-transporting ATPase
Other name:
histidine permease
Systematic name:
ATP phosphohydrolase (polar-amino-acid-importing)

Reactions

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.
