Summary[edit]
| Description |
English: Brass Kendrew model of an Arg-Phe peptide, placed on top of a stack of glass sheets with contours for the 2Å resolution electron density map of Staphylococcal nuclease, a primitive comparison before crystallographic computer graphics and even before the "Richards box" half-silvered mirror method. The arginine sidechain can be seen to hydrogen-bond between a backbone carbonyl O and the dark, triangular density of the nucleotide inhibitor of this enzyme. Photographed in 1968. |
