OE_3073R

Gene
OE_3073R
Protein
Dodecin
Organism
Halobacterium salinarum (strain ATCC 29341 / DSM 671 / R1)
Length
68 amino acids
Function
May function as storage protein that sequesters riboflavin and related compounds, thereby protecting the cell against undesirable reactions mediated by the free flavins. Binds and sequesters riboflavin, lumiflavin and lumichrome. Can also bind FAD and FMN (in vitro), but has low affinity for FAD and even lower affinity for FMN. Protects bound flavins against light damage; Trp-36 rapidly quenches the flavin excited state. Promotes the conversion of bound riboflavin to lumichrome.
Similarity
Belongs to the dodecin family.
