OphA in complex with SAM Monomer 5N0S

The structure of omphalotin A (OphA) reveals a complex catenane-like arrangement in which the peptide substrate is clamped with its amide nitrogen aligned for nucleophilic attack on the methyl group of SAM.  Model DescriptionThis 3D printed protein model of Omphalotin A (OphA) Monomer 1. This protein model set was designed to pair with the publication listed below matching Figure.1 and printed in full-color plastic.The dimer has a pseudo interlocking ring (catenane) arrangement. The first monomer of the two chain protein structure is colored to visualize the methyltransferase domain (orange), the clasp domain (green), and C-terminal substrate peptide (cyan). The active site of OphA and the ligand S-Adenosylmethionne (SAM) are colored by their atom type. (carbon = orange/yellow, nitrogen = blue and oxygen = red.)  The second chain of the dimer colors the same regions in different colors. The other monomer is colored pink (N-terminal methyltransferase domain) and gray (C-terminal clasp d
