CC -!- FUNCTION: Involved in protein export. Probably interacts with other
CC proteins to allow the postimport or conservative sorting pathway for
CC inner membrane proteins in plastids. Central subunit of the protein
CC translocation channel SecYE. Consists of two halves formed by TMs 1-5
CC and 6-10. These two domains form a lateral gate at the front which open
CC onto the bilayer between TMs 2 and 7, and are clamped together by SecE
CC at the back. The channel is closed by both a pore ring composed of
CC hydrophobic SecY resides and a short helix (helix 2A) on the
CC extracellular side of the membrane which forms a plug (By similarity).
CC {ECO:0000250, ECO:0000269|PubMed:21051552}.
CC -!- SUBUNIT: Part of a second Sec protein translocation apparatus.
CC Interacts probably with SECA2.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast membrane
CC {ECO:0000269|PubMed:21051552}; Multi-pass membrane protein
CC {ECO:0000269|PubMed:21051552}. Plastid, amyloplast membrane
CC {ECO:0000269|PubMed:21051552}; Multi-pass membrane protein
CC {ECO:0000269|PubMed:21051552}. Plastid, chloroplast thylakoid membrane
CC {ECO:0000269|PubMed:21051552}; Multi-pass membrane protein
CC {ECO:0000269|PubMed:21051552}. Note=Predominantly localized to envelope
CC membranes.
CC -!- TISSUE SPECIFICITY: Ubiquitous. {ECO:0000269|PubMed:21051552}.
CC -!- DISRUPTION PHENOTYPE: Embryo lethal. {ECO:0000269|PubMed:21051552}.
CC -!- MISCELLANEOUS: Cannot substitute for SCY1.
CC -!- SIMILARITY: Belongs to the SecY/SEC61-alpha family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAD24832.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
