Crystal structure of natural product Argyrin-D determined by 3D electron diffraction

<p>360&deg; rotation of the Argyrin D model (stick mode with carbon, yellow; nitrogen, blue; oxygen, red; sulfur, gold and hydrogen, white) defined by a 2Fo-Fc map contoured at 1.2 sigma (grey mesh). The model was refined at a resolution of 1.1&Aring; in Phenix using implemented electron scattering factors and restraints to R and Rfree values of 17.3 and 18.6%, respectively.</p>
