 Title    Strahleninduzierte Aggregatbildung von Proteinen: Bindung von Aminosäuren an Myoglobin Radiation-Induced Aggregation of Proteins: Binding of Amino Acids to Myoglobin  
 Abstract    When myoglobin is irradiated in the presence of amino acids, the most radiation-reactive species, like the aromatic and sulfur-containing amino acids, will bind preferentially to the protein. The radiation-induced binding is strongly dependent on the concentration of protein and amino acid. Subsequent to irradiation of myoglobin in the presence of radioactively labelled tryptophan followed by tryptic hydrolysis, only a single radioactive spot was detected on the fingerprint. The binding of amino acids is thus not randomly distributed over the protein molecule but occurs at specific reactive sites.

 Title    Conformational Changes in Proteins Induced by Low Temperatures: an Infrared Study  
 Abstract    Infrared spectra of hemoglobin (met-hemoglobin) and myoglobin were recorded in the temperature range —110 °C to 30 °C. On cooling hydroalcoholic solutions of hemoglobin, the spectra indicate a conformational change (revealed by the appearance of a band at 1665 cm ') com­ patible with the appearance of distortions in its a-helical structure. In the case of myoglobin smaller effects are ob­ served. These conformational changes are entirely revers­ ible and do not occur in frozen aqueous solutions.
