ENZYME: 7.4.2.1


ID   7.4.2.1
DE   ABC-type polar-amino-acid transporter.
AN   Histidine permease.
AN   Polar-amino-acid-transporting ATPase.
CA   ATP + H(2)O + polar amino acid-[polar amino acid-binding protein](Side 1)
CA   = ADP + phosphate + polar amino acid(Side 2) + [polar amino acid-binding
CA   protein](Side 1).
CC   -!- An ATP-binding cassette (ABC) type transporter, characterized by the
CC       presence of two similar ATP-binding domains/proteins and two integral
CC       membrane domains/proteins.
CC   -!- The enzyme, found in bacteria, interacts with an extracytoplasmic
CC       substrate binding protein and mediates the import of polar amino
CC       acids.
CC   -!- This entry comprises bacterial enzymes that import His, Arg, Lys,
CC       Glu, Gln, Asp, ornithine, octopine and nopaline.
CC   -!- Formerly EC 3.6.3.21.
