Russupteridine IV Chemical Properties,Usage,Production

Description

6,7-dimethyl-8-Ribityllumazine (DMRL) is a natural chromophore of lumazine protein (LumP), a fluorescent accessory protein that induces a blue shift (495 to 475 nm) in luciferase emission wavelengths in bioluminescent Photobacterium. DMRL binds noncovalently to both the N- and C-terminal domains of LumP. It is also a biosynthetic precursor of riboflavin and substrate of riboflavin synthase.

Uses

6,7-Dimethyl-8-ribityllumazine serves as fluorophore in Lumazine (L473800) proteins (LumP) of luminescent bacteria.

Definition

ChEBI: 6,7-dimethyl-8-(1-D-ribityl)lumazine is the pteridine that is lumazine substituted with methyl groups at C-6 and -7 and with a 1-D-ribityl group on N-8. It has a role as an Escherichia coli metabolite and a cofactor. It is functionally related to a lumazine and a ribitol. It is a conjugate acid of a 6,7-dimethyl-8-(1-D-ribityl)lumazine(1-).
