violacein Chemical Properties,Uses,Production
Description
Violacein is a naturally occurring di-indole-pyrrole violet-blue colored pigment that possesses numerous biological functions such as antimicrobial, antiviral, anticancer, antiulcerogenic, anti-leishmanial, and enzyme modulation properties (Narsing et al. 2017). Violacein is biosynthesized by bacterial species such as Chromobacterium violaceum, Collimonas sp., Pseudoalteromonas sp., Pseudomonas aeruginosa, and Janthinobacterium sp. This natural pigment is used extensively in the cosmetic, food, pharmaceutical, and textile industries (Baiano 2014).
Uses
Violacein is an intense violet pigment formed by the condensation of two tryptophan units, found in a number of bacteria, notably Chromobacterium violaceum. The regulation of pigment biosynthesis is the chromogenic basis for the use of C. violaceum CV26 for the detection of quorum sensing mediators. Violacein exhibits broad spectrum actvity against bacteria, protozoans (including malaria), viruses and mammalian cell lines. Violacein cell toxicity resembles TNF-α signal transduction.
Definition
ChEBI: violacein is a member of the class of hydroxyindoles resulting from the formal oxidative coupling between the 3-position of 1,3-dihydro-2H-indol-2-one and the 3-position of 1,3-dihydro-2H-pyrrol-2-one, which is substituted at the 5 position by a 5-hydroxy-1H-indol-3-yl group, where the newly-formed double bond has E configuration. It is a purple chromobacterial pigment that has antibacterial, antifungal, antiprotozoan, and anticancer properties.
General Description
Violacein from Janthinobacterium lividum is used as a colorant for natural and synthetic fabrics. It functions as a respiratory pigment and regulates tryptophan production. Violacein exhibits anti-protozoal activity.
