BRITE hierarchy
Sysname
ATP phosphohydrolase (chloroplast protein-importing)
Reaction(IUBMB)
ATP + H2O = ADP + phosphate [RN:R00086]
Reaction(KEGG)
Substrate
ATP [CPD:C00002];
H2O [CPD:C00001]
Product
ADP [CPD:C00008];
phosphate [CPD:C00009]
Comment
A non-phosphorylated, non-ABC (ATP-binding cassette) ATPase that is involved in protein transport. Involved in the transport of proteins or preproteins into chloroplast stroma (several ATPases may participate in this process).
