Metabolite Identification
Common NameProviolacein
DescriptionProviolacein is a member of the indole alkaloid chemical class, specifically a pigment produced in the violacein biosynthetic pathway. Its chemical structure features a complex arrangement of indole rings, which are crucial for its colorimetric properties. The biosynthesis of proviolacein involves several key enzymes, including VioD, a flavin-dependent oxygenase that catalyzes the hydroxylation of prodeoxyviolaceinic acid at the 5-position of one indole ring to yield proviolacein (PMID:25664787 ). Subsequently, VioC acts on the other indole ring to facilitate the conversion to violacein (PMID:17176066 ). Proviolacein has been utilized in various applications, including a dual-color biosensor for detecting environmental lead, where its biosynthetic gene cluster was transcriptionally fused to a Pb(II) responsive element in Escherichia coli (PMID:37577420 ). Additionally, proviolacein's generation has been evaluated as a colorimetric output in comparison to other compounds like lycopene (PMID:38782713 ). Enhanced production methods have led to significant yields of proviolacein, contributing to its potential use in biotechnological applications (PMID:33399465 ).
