Description: The animation submitted illustrates an enzyme molecule, Epidermin biosynthesis protein (EpiD) combining with its coenzyme, riboflavin mononucleotide (FMN). The green molecule is ‘FMN’ and the red molecule is ‘EpiD’. FMN is made from riboflavin, which uses vitamin B2 to form in human body. The coenzyme activated its enzyme, so that it can function properly. References: Tags: Comments:
