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.

The targeting and directed movement of proteins into a cell or organelle. Not all import involves an initial targeting event.

The directed movement of a bacteriocin into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Bacteriocins are a group of antibiotics produced by bacteria and are encoded by a group of naturally occurring plasmids, e.g. Col E1. Bacteriocins are toxic to bacteria closely related to the bacteriocin producing strain.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a bacteriocin stimulus. A bacteriocin is a protein substance released by certain bacteria that kills but does not lyse closely related strains of bacteria. Specific bacteriocins attach to specific receptors on cell walls and induce specific metabolic block, e.g. cessation of nucleic acid or protein synthesis of oxidative phosphorylation.

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.

The eventual plane of cell division (also known as cell cleavage or cytokinesis) in a dividing cell. In Eukaryotes, the cleavage apparatus, composed of septin structures and the actomyosin contractile ring, forms along this plane, and the mitotic, or meiotic, spindle is aligned perpendicular to the division plane. In bacteria, the cell division site is generally located at mid-cell and is the site at which the cytoskeletal structure, the Z-ring, assembles.

A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which at least one component is a protein and the constituent parts function together.

The region between the inner (cytoplasmic) and outer membrane (Gram-negative Bacteria) or cytoplasmic membrane and cell wall (Fungi and Gram-positive Bacteria).
