IntEnz Enzyme Nomenclature


Accepted name:
ABC-type L-arabinose transporter
Other names:
L-arabinose transporting ATPase
L-arabinose ABC transporter
araFGH (gene names)
Systematic name:
ATP phosphohydrolase (ABC-type, L-arabinose-importing)



ATP-binding cassette (ABC) type transporter, characterized by the presence of two similar ATP-binding domains/proteins and two integral membrane domains/proteins. A bacterial enzyme that interacts with an extracytoplasmic substrate binding protein and mediates the high-affinity uptake of L-arabinose. Formerly EC
