molecular function |
| GO:0020037 | | heme binding | | Interacting selectively and non-covalently with heme, any compound of iron complexed in a porphyrin (tetrapyrrole) ring. |
| GO:0016151 | | nickel cation binding | | Interacting selectively and non-covalently with nickel (Ni) cations. |
| GO:0015197 | | peptide transporter activity | | Enables the directed movement of peptides, compounds of two or more amino acids where the alpha carboxyl group of one is bound to the alpha amino group of another, into, out of or within a cell, or between cells. |
| GO:0046914 | | transition metal ion binding | | Interacting selectively and non-covalently with a transition metal ions; a transition metal is an element whose atom has an incomplete d-subshell of extranuclear electrons, or which gives rise to a cation or cations with an incomplete d-subshell. Transition metals often have more than one valency state. Biologically relevant transition metals include vanadium, manganese, iron, copper, cobalt, nickel, molybdenum and silver. |
biological process |
| GO:0050919 | | negative chemotaxis | | The directed movement of a motile cell or organism towards a lower concentration of a chemical. |
| GO:0015675 | | nickel cation transport | | The directed movement of nickel (Ni) cations into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. |
| GO:0015833 | | peptide transport | | The directed movement of peptides, compounds of two or more amino acids where the alpha carboxyl group of one is bound to the alpha amino group of another, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. |
| GO:0055085 | | transmembrane transport | | The process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other |
| GO:0006810 | | transport | | The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter, pore or motor protein. |
cellular component |
| GO:0043190 | | ATP-binding cassette (ABC) transporter complex | | 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 | | outer membrane-bounded periplasmic space | | 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:0042597 | | periplasmic space | | The region between the inner (cytoplasmic) and outer membrane (Gram-negative Bacteria) or cytoplasmic membrane and cell wall (Fungi and Gram-positive Bacteria). |
