Figure 3From: The DNA-repair protein AlkB, EGL-9, and leprecan define new families of 2-oxoglutarate- and iron-dependent dioxygenasesTopological diagrams for three members of the 2OG-Fe(II) dioxygenase superfamily. The diagrams are based on the experimentally determined structures for E. nidulans isopenicillin N synthase (PDB: 1ips) and structural models of prolyl-4-hydroxylase and AlkB. The amino acid residues of the active site and the Fe(II) ion are shown as in Figure 2.Back to article page
