EC 7.6.2.5 Details

show Brenda entry

EC number

7.6.2.5

Accepted name

ABC-type heme transporter

Reaction

ATP + H₂O + heme_{[side 1]} = ADP + phosphate + heme_{[side 2]}

Other name(s)

heme-transporting ATPase

Systematic name

ATP phosphohydrolase (ABC-type, heme-exporting)

Comment

An ATP-binding cassette (ABC) type transporter, characterized by the presence of two similar ATP-binding domains/proteins and two integral membrane domains/proteins. Does not undergo phosphorylation during the transport process. The enzyme has been described from Gram-negative bacteria and green plants.

History

created 2000 as EC 3.6.3.41, transferred 2018 to EC 7.6.2.5
