Glycosyltransferase (GlcNAc). GlcNAc is an enzyme that carries out the first glycosylation step of hydroxylated Skp1, a ubiquitous eukaryotic protein, in the cytoplasm.
DDE superfamily endonuclease. This family of proteins are related to pfam00665 and are probably endonucleases of the DDE superfamily. Transposase proteins are necessary for efficient DNA transposition. This domain is a member of the DDE superfamily, which contain three carboxylate residues that are believed to be responsible for coordinating metal ions needed for catalysis. The catalytic activity of this enzyme involves DNA cleavage at a specific site followed by a strand transfer reaction. Interestingly this family also includes the CENP-B protein. This domain in that protein appears to have lost the metal binding residues and is unlikely to have endonuclease activity. Centromere Protein B (CENP-B) is a DNA-binding protein localized to the centromere.
