abstract L-dopa decarboxylase has been purified to homogeneity from post mortem removed human kidneys. Homogeneity was examined by polyacrylamide gel electrophoresis (PAGE) analysis both in the presence and absence of SDS. The enzyme has a molecular weight of 100,000 daltons estimated by gel filtration and 50,000 daltons determined after SDS-PAGE. Human L- dopa decarboxylase therefore is a dimer. Polyclonal antibodies produced against human L-dopa decarboxylase react with the 50,000 daltons enzyme subunit after immuno-blotting and also precipitates enzyme activity. Activity against L-dopa is partially inhibited by 5-hydroxytryptophan (5-HTP). The effect of various cations on L-dopa decarboxylase activity has also been tested.
