CC   -!- FUNCTION: The central subunit of the protein translocation channel
CC       SecYE. Consists of two halves. These two domains form a lateral gate at
CC       the front which open onto the bilayer between TMs 2 and 7, and are
CC       clamped together by SecE at the back. The channel is closed by both a
CC       pore ring composed of hydrophobic SecY resides and a short helix (helix
CC       2A) on the extracellular side of the membrane which forms a plug (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Component of the plastid Sec protein translocase complex,
CC       which is composed of at least SecY and SecE. {ECO:0000255|HAMAP-
CC       Rule:MF_01465}.
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}.
CC   -!- CAUTION: Bioinformatics prediction programs detect only 8 instead of 10
CC       transmembrane regions. {ECO:0000305}.
