PROTEIN MODIFYING ENZYME

摘要

The present invention relates, in general, to a protein prenyltransferase and, in particular, to protein geranylgeranyltransferase (GGTase I) and to a nucleic acid sequence encoding same. The invention also relates to methods of producing GGTase-I and geranylgeranyl modified polypeptides. The invention further relates to a method of screening compounds for the ability to alter GGTase-I activity.
