Flavokinase / RFK Protein Description

Flavokinase belongs to the transferases family. It contains 220 amino acids. Its secondary structure contains 69 residues in alpha helix form, and 60 residues a beta sheet conformation. T Flavokinase is an essential enzyme that catalyzes the phosphorylation of riboflavin (vitamin B2) to form flavin mononucleotide (FMN), an obligatory step in vitamin B2 utilization and flavin cofactor synthesis. It has been proposed that TNF, through the activation of the flavokinase gene, enhances the incorporation of FAD in NADPH oxidase enzymes, which is a critical step for the assembly and activation of NADPH oxidase.
