Riboflavin kinase (RFK) is an essential enzyme catalyzing the phosphorylation of riboflavin (vitamin B(2)) to form FMN, an obligatory step in vitamin B(2) utilization and flavin cofactor synthesis. The structure of human RFK revealed a six-stranded antiparallel beta barrel core structurally similar to the riboflavin synthase/ferredoxin reductase FAD binding domain fold ...
