• ligand
  • Complex 1 displays the intradiol-cleaving dioxygenase activity, and the coordinate ethoxyl arm of the ligand is capable of accepting the proton from catechol, which mimics the function of Tyr447 in the. (diva-portal.org)
  • dioxygenases
  • The structures of the 4-CCD complexes show that the catechols bind the catalytic iron ion in a bidentate mode displacing Tyr169 and the benzoate ion (found in the native enzyme structure) from the metal coordination sphere, as found in other adducts of intradiol dioxygenases with substrates.
