colicin


Also found in: Dictionary, Encyclopedia, Wikipedia.

col·i·cin

(kol'i-sin),
Bacteriocin produced by strains of Escherichia coli and by other enterobacteria (Shigella and Salmonella) that carry the necessary plasmids. Many are toxic to related bacterial strains and bind to specific cellular receptors interfering with normal function.

colicin

(kŏl′ĭ-sĭn, kō′lĭ-)
n.
Any of various antibacterial proteins produced by certain strains of E. coli that inhibit or kill closely related species or strains of bacteria.
