WebMar 1, 2013 · The crystal structure of chicken liver sulfite oxidase indicated that this residue, Cys185 in chicken SO, coordinates the Mo atom in the active site. To improve our understanding of the role of this residue in the catalytic mechanism of sulfite oxidase, serine and alanine variants at more » position 185 of recombinant chicken SO were generated. WebJan 21, 2002 · Phenoloxidase (1) oxidizes tyrosine to dopa and then to dopaquinone. Dopaquinone undergoes cyclization to form dopachrome via leucodopachrome. Dopachrome (decarboxylating) isomerase (2) catalyses the isomerization of dopachrome to quinone methide which is then converted to DHI. DHI is further oxidized to indolequinones … covey is significant to douglass because:
