title: Molecular graphics: application to the structure determination of a snake venom neurotoxin.
abstract: Atomic coordinates have been determined for a snake venom alpha-neurotoxic protein by fitting a molecular model to a crystallographically derived 2.2-angstrom electron density map. The fitting was carried out entirely on a computer-operated molecular, graphics system without going through any mechanical model stage.
