... 1-substituted imidazole on the iron of 13G10±Fe(ToCPP) is even more difđcult than the binding of two 1-substituted imidazoles on the iron of free Fe(ToCPP). In addition, the in¯uence of the nature of the substituent ... distortion of the porphyrin ring and a shift of the iron atom outside the plane of the porphyrin. Binding of imidazole to the iron( III) of Fe(ToCPP), a,a-1,2- a,b-1,2-Fe(DoCPP), Fe(MoCPP) and to their ... (Table 1). The bind- ing of the ®rst CN ± ligand to the iron was thus more easy in the hydrophobic binding pocket of the antibody than the binding of the second one, most probably because of the steric...

... interesting that the )10 sequence is located inside the iron box of desA (nucleotides 7–12 of the iron box), explaining the regulation of desA expression by binding of DmdR1 to the iron box. The same ... mediated by binding of the regulatory protein DmdR1 to the iron box located in the promoter region of the desABCD cluster. Elec- trophoretic mobility-shift assays of the desA promoters of both S. coelicolor ... a wild-type copy of the desA gene to complement the mutation in trans suggests that the DdesA mutation affects expression of the downstream genes desBCD in the des cluster and that the presence of wild-type...
