| 1.13.11.50 | E98Q |
an interplay of residues Glu98, His104, Glu11 (from the neighbor subunit), and Arg80 is the most important for the Fe2+ transport in and out of the protein |

| 1.13.11.50 | F115A |
site-directed mutagenesis, the mutant shows reduced turnover and altered iron binding compared to the wild-type enzyme |
725553 |
| 1.13.11.50 | F119A |
site-directed mutagenesis, the mutant shows reduced turnover and altered iron binding compared to the wild-type enzyme |

| 1.13.11.50 | F59A |
site-directed mutagenesis, the mutant shows reduced turnover and altered iron binding compared to the wild-type enzyme |
725553 |
| 1.13.11.50 | H104E |
no activity in initial rate assays with substrate pentan-2,4-dione, no binding of Fe2+ at binding site I, small effect on other metal ions |
696107 |
| 1.13.11.50 | H104N |
approximately 1% of the specific activity of wild-type enzyme with substrate pentan-2,4-dione, retains binding affinity for Fe2+ at binding site I, binding seems to be tighter than in wild-type, small effect on other metal ions |
696107 |
| 1.13.11.50 | H62E |
no activity in initial rate assays with substrate pentan-2,4-dione, no binding of Fe2+ at binding site I, small effect on other metal ions |
