7.4.2.4 |
| Accepted name: |
chloroplast protein-transporting ATPase |
| Reaction: |
ATP + H2O + chloroplast-protein[side 1] = ADP + phosphate + chloroplast-protein[side 2] |
| Systematic name: |
ATP phosphohydrolase (chloroplast protein-importing) |
| Comments: |
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). |
