ArgC 3D structure (PDB 2NQT). Crystal structure generated by Cherney et al. (2006) by X-ray diffraction of full-length protein. Flat arrow shapes represent beta sheets, corkscrews represent alpha helices, and other parts are unstructured. Magenta and blue: ArgC chains A and B, respectively. Green: epitope 595988. Black stars at end of green epitopes: Residue 20 (Y20H in Ravenel). Partial complex of 2NQT shown over full complex of 7NNI used in DDG predictions for visual clarity.
