CRYSTAL STRUCTURE OF HUMAN CYTOSOLIC 5'-NUCLEOTIDASE II (NT5C2, CN-II)

Overview

Cytosolic 5'-nucleotidase II catalyzes the dephosphorylation of, 6-hydroxypurine nucleoside 5'-monophosphates and regulates the IMP and GMP, pools within the cell. It possesses phosphotransferase activity and, thereby also catalyzes the reverse reaction. Both reactions are, allosterically activated by adenine-based nucleotides and, 2,3-bisphosphoglycerate. We have solved structures of cytosolic, 5'-nucleotidase II as native protein (2.2 Angstrom) and in complex with, adenosine (1.5 Angstrom) and beryllium trifluoride (2.15 Angstrom) The, tetrameric enzyme is structurally similar to enzymes of the haloacid, dehalogenase (HAD) superfamily, including mitochondrial, 5'(3')-deoxyribonucleotidase and cytosolic 5'-nucleotidase III but, possesses additional regulatory regions that contain two ...
