Molybdenum hydroxylases in Drosophila

A reliable method for visualizing the Drosophila enzyme pyridoxal oxidase in polyacrylamide gels is described. Antiserum to pyridoxal oxidase has been produced and used in quantitative immunoelectrophoresis to determine the relative amounts of pyridoxal oxidase cross reacting material (CRM) in several mutants including lpo, lxd, ma-l and cin. The lpo variant did not have CRM for PO, thus further supporting the idea that it represents a structural gene for pyridoxal oxidase in Drosophila. CRM for PO was found in ma-l and lxd indicating that their effects upon the enzyme are probably post-translational. No CRM for PO could be found in the cin mutants.
