UniProt Comments
Involved in protein export. Probably interacts with other proteins to allow the translocation of proteins across the chloroplast thylakoid membranes. Required for normal greening during embryogenesis. Central subunit of the protein translocation channel SecYE. Consists of two halves formed by TMs 1-5 and 6-10. These two domains form a lateral gate at the front which open onto the bilayer between TMs 2 and 7, and are clamped together by SecE at the back. The channel is closed by both a pore ring composed of hydrophobic SecY resides and a short helix (helix 2A) on the extracellular side of the membrane which forms a plug .
