FIG. 14. — Comparison between MnPs and FePs. (A) Growth of wild-type E. coli AB1157 in casamino acids (M9CA) medium in the presence of 25 μM of ortho (H₂O)MnTM-2-PyP⁵⁺, or ortho, meta, and para (OH)FeTMPyP⁴⁺ under anaerobic conditions. The other axial ligand in MnPs and FePs is water molecule. Identical data were obtained with the JI132 SOD-deficient strain (not shown); anaerobically with and without MnTM-2-PyP⁵⁺ the SOD-deficient strain grows as well as wild type. (B) Structures of ortho, meta, and para (OH)FeTMPyP⁴⁺ and ortho (OH)FeTE-2-PyP⁵⁺. (C) Effect of (H₂O)MnTM-2-PyP⁵⁺, (H₂O)MnTE-2-PyP⁵⁺, (OH)FeTM-2-PyP⁵⁺, and (OH)FeTE-2-PyP⁵⁺ at 25 μM on the aerobic growth of SOD-deficient E. coli JI132 in 5AA medium. A_700nm after 56 h of growth is shown. Adapted from ref. (19).
