Violacein is a violet pigment produced by several bacteria through pathway of 5 related genes, vioA, vioB, vioC, vioD and vioE. It was initially discovered in Chromobacterium violaceum. This metabolite of tryptophan has such special applications as antibacterial, anti-trypanocidal, anti-ulcerogenic, and anticancer drugs.

Vio D with Membrane Anchor 6

This part is composed with two parts, the Membrane Anchor 6 and Violacein synthetic pathway enzyme vioD. The enzyme can be aggregated with other membrane anchors, composing the Membrane Magic system.

Violacein biosynthetic pathway

Violacein is a violet pigment produced by several bacteria through pathway of 5 related genes, vioA, vioB, vioC, vioD and vioE. It was initially discovered in Chromobacterium violaceum. This metabolite of tryptophan has such special applications as antibacterial, anti-trypanocidal, anti-ulcerogenic, and anticancer drugs.

The violacein biosynthetic pathway includes 5 key enzymes which work in conjunction. VioA, a flavoenzyme and VioB, a heme protein, work together to oxidize and dimerize tryptophen into IPA imine dimer. Then vioE induces a indole rearrangement,producing prodeoxyviolacein acid, also known as PVA.

VioD that we insert in this part belongs to the last 2 enzymes in this pathway that produce the final main product,violacein.It is a flavin-dependent oxygenase that hydroxylates 5-position indole ring, then the other 2-position indole ring is processed by VioC(see BBa_K771205) to create the oxindole,thus violacein is synthesized.
