a 3-D structure of SAF modeled with SWISS-MODEL using homology modeling based on the template ribonucleotide reductase class 1b holocomplex R1E, R2F from Salmonella typhimurium (PDB ID: 2bq1.1.B) (b) CD spectra of recombinant SAF protein purified by Ni-NTA chromatography. The far UV CD spectrum of SAF protein analyzed by k2d2 software revealed that the secondary structure contained 49% α-helix, 17.8% β-strand and 33.2% random coil
