KEGG   ENZYME: 7.4.2.4
Entry
EC 7.4.2.4                  Enzyme                                 
Name
chloroplast protein-transporting ATPase
Class
Translocases;
Catalysing the translocation of amino acids and peptides;
Linked to the hydrolysis of a nucleoside triphosphate
Sysname
ATP phosphohydrolase (chloroplast protein-importing)
Reaction(IUBMB)
ATP + H2O + chloroplast-protein[side 1] = ADP + phosphate + chloroplast-protein[side 2]
Substrate
ATP [CPD:C00002];
H2O [CPD:C00001];
chloroplast-protein[side 1]
Product
ADP [CPD:C00008];
phosphate [CPD:C00009];
chloroplast-protein[side 2]
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).
History
EC 7.4.2.4 created 2000 as EC 3.6.3.52, transferred 2018 to EC 7.4.2.4
