Structure and transport mechanism of human riboflavin transporters [PDF]

Nature Communications
Riboflavin (vitamin B2) is the precursor of flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD), which act as key cofactors of many enzymes, thus has essential roles in cell growth and functions. Animals cannot synthesize riboflavin in situ,

Role of riboflavin biosynthesis gene duplication and transporter in Aeromonas salmonicida virulence in marine teleost fish

Virulence, 2023
Active flavins derived from riboflavin (vitamin B2) are essential for life. Bacteria biosynthesize riboflavin or scavenge it through uptake systems, and both mechanisms may be present.

Corneal absorption of a new riboflavin-nanostructured system for transepithelial collagen cross-linking. [PDF]

PLoS ONE, 2013
Corneal collagen cross-linking (CXL) has been described as a promising therapy for keratoconus. According to standard CXL protocol, epithelium should be debrided before treatment to allow penetration of riboflavin into the corneal stroma.

Co-Overexpression of RIB1 and RIB6 Increases Riboflavin Production in the Yeast Candida famata

Fermentation, 2022
Riboflavin or vitamin B2 is a water-soluble vitamin and a precursor of flavin coenzymes, flavin mononucleotide, and flavin adenine dinucleotide, which play a key role as enzyme cofactors in energy metabolism.
