  • GO:0031522 A transmembrane protein complex involved in the translocation of proteins across the cytoplasmic membrane. In Gram-negative bacteria, Sec-translocated proteins are subsequently secreted via the type II, IV, or V secretion systems. Sec complex components include SecA, D, E, F, G, Y and YajC.
  • GO:0005737 The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
  • GO:0005886 The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
  • GO:0005524 Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
  • GO:0046872 Binding to a metal ion.
  • GO:0008564 Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: ATP + H2O + protein+(in) = ADP + phosphate + protein+(out); drives the concomitant secretion of proteins.
  • GO:0065002 The directed movement of proteins in a cell, from one side of a membrane to another by means of some agent such as a transporter or pore.
  • GO:0017038 The targeting and directed movement of proteins into a cell or organelle. Not all import involves an initial targeting event.
  • GO:0006605 The process of targeting specific proteins to particular regions of the cell, typically membrane-bounded subcellular organelles. Usually requires an organelle specific protein sequence motif.
  • GO:0043952 The process in which unfolded proteins are transported across the cytoplasmic membrane in Gram-positive and Gram-negative bacteria by the Sec complex, in a process involving proteolytic cleavage of an N-terminal signal peptide.
  • GO:0016020 A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it.
  • GO:0006886 The directed movement of proteins in a cell, including the movement of proteins between specific compartments or structures within a cell, such as organelles of a eukaryotic cell.
