Mechanism, Structure, and Inhibition of O-GlcNAc Processing Enzymes.

ABSTRACT: The post-translational modification of nucleocytoplasmic proteins with O-linked 2-acetamido-2-deoxy-d-glucopyranose (O-GlcNAc) is a topic of considerable interest and attracts a great deal of research effort. O-GlcNAcylation is a dynamic process which can occur multiple times over the lifetime of a protein, sometimes in a reciprocal relationship with phosphorylation. Several hundred proteins, which are involved in a diverse range of cellular processes, have been identified as being modified with the monosaccharide. The control of the O-GlcNAc modification state on different protein targets appears to be important in the aetiology of a number of diseases, including type II diabetes, neurodegenerative diseases and cancer. Two enzymes are responsible for the addition and removal of the O-GlcN
