Structural representation of P. kullae K24 AzoB for dinucleotide binding. A, shows cartoon structure of AzoB, in which the key residues for NADPH binding are colored. B, in the AzoB-NADPH complex, there is a wide exposed cleft adjacent to the nicotinamide moiety. C, the alignment of the glycine-rich pyrophosphate-binding sequences from the enzymes studied. The secondary structure assignment is based on the AzoB. The residues related to NADPH binding are boxed.
