Fig. 2From: Azoreductase: a key player of xenobiotic metabolismCrystal structure of dimeric flavin-dependent azoreductase (AzrA) (PDB 3W77): green and blue are the monomers of FMN-containing azoreductase bound to each other and form a dimer. All flavin-containing azoreductases are dimeric as the FMN is bound in an active site formed by the two monomersBack to article page
