GO
GO:0043190 A complex for the transport of metabolites into and out of the cell, typically comprised of four domains; two membrane-associated domains and two ATP-binding domains at the intracellular face of the membrane, that form a central pore through the plasma membrane. Each of the four core domains may be encoded as a separate polypeptide or the domains can be fused in any one of a number of ways into multidomain polypeptides. In Bacteria and Archaebacteria, ABC transporters also include substrate binding proteins to bind substrate external to the cytoplasm and deliver it to the transporter. GO:0030288 The region between the inner (cytoplasmic or plasma) membrane and outer membrane of organisms with two membranes such as Gram negative bacteria. These periplasmic spaces are relatively thick and contain a thin peptidoglycan layer (PGL), also referred to as a thin cell wall. GO:1904680 Enables the transfer of a peptide from one side of a membrane to the other. GO:0042938 The directed movement of a dipeptide, a combination of two amino acids by means of a peptide (-CO-NH-) link, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. GO:0015031 The directed movement of proteins into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. GO:0055085 The process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other.
