Dark Reddish/Brown Crystalline Solid

An analog known to compete with Riboflavin in Lactobacillus casei. Riboflavin kinase substrate and inhibitor

Has weak antibacterial activity against some gram-positive bacteria, especially Staphylococcus aureus, Sarcina latea, Bacillus cereus, and Bacillus subtilis. Also exhibits antiriboflavin activity and inhibits the biosynthesis of riboflavin by a r

Roseoflavin is an antibacterial pigment isolated from Streptomyces davawensis as an anti-metabolite of riboflavin. Roseoflavin is used as a substrate to mimic riboflavin in flavin biosynthesis, but leading to the formation of inactive flavin co-factors. More recently, roseoflavin has been shown to be an important regulator of bacterial gene expression by binding to untranslated regions of RNA, so-called ribo-switching sites.

ChEBI: A benzopteridine that is riboflavin in which the methyl group at position 8 is substituted by a dimethylamino group.
