The majority of proteins that are secreted across the bacterial cytoplasmic membrane leave the cell via the Sec pathway. which in its minimal form consists of the dimeric ATP-driven motor protein SecA that associates with the protein-conducting membrane pore SecYEG. Some Gram-positive bacteria contain two homologues of SecA. termed SecA1 and SecA2. https://www.nacrack.com/flash-deal-Diamond-Painting-Zee-en-strand-special-find/
