CC   -!- FUNCTION: The central subunit of the protein translocation channel
CC       SecYE. Consists of two halves formed by TMs 1-5 and 6-10. These two
CC       domains form a lateral gate at the front which open onto the bilayer
CC       between TMs 2 and 7, and are clamped together by SecE at the back. The
CC       channel is closed by both a pore ring composed of hydrophobic SecY
CC       resides and a short helix (helix 2A) on the extracellular side of the
CC       membrane which forms a plug. {ECO:0000255|HAMAP-Rule:MF_01465}.
CC   -!- SUBUNIT: Component of the plastid Sec protein translocase complex,
CC       which is composed of at least SecY, SecE and SecG. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC       {ECO:0000255|HAMAP-Rule:MF_01465}; Multi-pass membrane protein
CC       {ECO:0000255|HAMAP-Rule:MF_01465}.
CC   -!- SIMILARITY: Belongs to the SecY/SEC61-alpha family. {ECO:0000255|HAMAP-
CC       Rule:MF_01465}.
