Crystal structure study of Opsanus tau parvalbumin by multiwavelength anomalous diffraction
Year: 1985
Type: article
Abstract: The crystal structure of a small calcium-binding protein, the parvalbumin IIIf from Opsanus tau in which Tb was substituted for Ca, has been analysed by multiwavelength anomalous diffraction. Data at a resolution of 2.3 A were collected at three wavelengths near the L3 absorption edge of Tb (1.645-1.650 A), using the synchrotron radiation emitted by a storage ring and a multiwire proportional counter. The phases of the reflections were determined from this single derivative, without native data. Prior to any refinement, the resulting electron density map shows a good agreement with the model of the homologous carp parvalbumin in regions of identical amino-acid sequence.
