Protein Family Models for Protein (Select 1718691841) - Protein Family Models

Select item 4172491.

This family corresponds to the N terminal domain of the bifunctional enzyme riboflavin kinase / FAD synthetase. These enzymes have both ATP:riboflavin 5'-phospho transferase and ATP:FMN-adenylyltransferase activity [1]. They catalyse the 5'-phosphorylation of riboflavin to FMN and the adenylylation of FMN to FAD [1]. This domain is thought to have the flavin mononucleotide (FMN) adenylyltransferase activity [2].

riboflavin kinase

This family represents the C-terminal region of the bifunctional riboflavin biosynthesis protein known as RibC in Bacillus subtilis. The RibC protein from Bacillus subtilis has both flavokinase and flavin adenine dinucleotide synthetase (FAD-synthetase) activities. RibC plays an essential role in the flavin metabolism [1]. This domain is thought to have kinase activity [2]. [1]. 9473052. Regulation of riboflavin biosynthesis in Bacillus subtilis is. affected by the activity of the flavokinase/flavin adenine. dinucleotide synthetase encoded by ribC.. Mack M, van Loon AP, Hohmann HP;.
