title: [X-ray analysis of pepsin. VI. Atomic structure of the enzyme at 2-angstrom resolution].
abstract: The crystallographic refinement of pepsin structure at 2 A resolution is described. Real space refinement and Jack and Levitt methods were used. As a result, the refined atomic coordinates of 2436 nonhydrogen atoms were obtained. Values of crystallographic R-factor and conformational energy are 29.2% and -1347 kcal/mol correspondingly. The most important and interesting features of pepsin structure are discussed.
