16475804 Analysis of recombinant G473D sulfite oxidase indicated that it is severely impaired both in the ability to bind sulfite and in catalysis, with a second-order rate constant 5 orders of magnitude lower than that of the wild type.
16229463 mutations to charged residues at the equivalent sites most likely cause crucial global or localized structural changes, and expose an alternative docking site that may compete with the Mo domain for docking of the heme
