Figure 7.
Structures of enoyl-ACP reductases. Top: FabI from E. coli (PDB: 2FHS), FabL from B. subtilis (PDB: 3OIC) and FabV from X. oryzae (PDB: 3S8M) are all members of the SDR superfamily, utilizing NAD(P)H. Whereas FabI and FabL are tetramers, FabV is a monomer. ClustalOmega was used to generate a sequence identity matrix, including FAS1y (the yeast FAS ER), FAS1h (the human FAS ER) and MER (the human mitochondrial ER). Bottom: The ER dimer in type I FAS from pig (2VZ8) is shown in pink/purple, and FabK from S. pneumoniae (2Z6I).
