Imine reductase
An imine reductase (IRED) is an enzyme that reduces imines to amines.[1][2] This family of enzymes is employed in the industrial production of amine-containing pharmaceuticals.[3] The IRED enzymes that are found to catalyze both imine formation and imine reduction are called reductive aminases (RedAms).
Discovery
[edit]IREDs were originally discovered in 2010 by screening bacterial strains for reducing activity on 2-methyl-1-pyrroline (2-MPN).[4][5] Based on each member's ability to reduce 2-MPN to (R)- or (S)-2-methylpyrrolidine they are designated as R-selective or S-selective, respectively.[6][7]
Applications
[edit]IREDs have been employed to reduce imines formed from ketone-amine mixtures.[1][2] The conversion is not a genuine reductive amination as only the second half of the two-part reaction is catalyzed. In 2017 an IRED was discovered that catalyzed both steps of reductive amination of a wide scope of ketone-amine pairs.[8] These are dubbed reductive aminases (RedAms).[1][2] Engineered RedAms have been employed in industrial processes to support production of pharmaceuticals for clinical trials and commercial manufacturing.[9][10]
Structure
[edit]IREDs are dimeric enzymes with each protomer having an N-terminal Rossmann nucleotide-binding domain and a C-terminal dimerization domain joined by a long interdomain α-helix.[3][11] Each protomer's α-helical dimerization domain wraps around the interdomain helix of its dimer partner forming the substrate-binding cleft above the NAD(P)H cofactor binding site in the Rossmann domain. 3-Hydroxybutyrate dehydrogenases have similar N-terminal nucleotide-binding and C-terminal dimerization domains, but do not share the extensive dimerization interface of IREDs.[12]
