RL   Submitted (NOV-2003) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Has a central role in coupling the hydrolysis of ATP to the
CC       transfer of proteins across the thylakoid membrane. {ECO:0000255|HAMAP-
CC       Rule:MF_01382}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + H2O + cellular proteinSide 1 = ADP + phosphate +
CC         cellular proteinSide 2.; EC=7.4.2.8; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_01382};
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast stroma {ECO:0000255|HAMAP-
CC       Rule:MF_01382}. Plastid, chloroplast thylakoid membrane
CC       {ECO:0000255|HAMAP-Rule:MF_01382}; Peripheral membrane protein
CC       {ECO:0000255|HAMAP-Rule:MF_01382}. Note=A minor fraction is associated
CC       with the chloroplast thylakoid membrane. {ECO:0000255|HAMAP-
CC       Rule:MF_01382}.
CC   -!- SIMILARITY: Belongs to the SecA family. {ECO:0000255|HAMAP-
CC       Rule:MF_01382}.
