The absorption spectra of immune proteins.
Since the absorption spectra of simple proteins are known to depend on their content of the three aromatic amino acids, tyrosine, tryptophane, and phenylalanine, it was of interest to examine the group of purified immune proteins which weie available in order to determine whether differences in their composition could be found by this method. These proteins, all of which arc associated with imm...
متن کاملThe ultraviolet absorption spectra of proteins.
The absorption spectra of proteins have been made the subject of considerable study. For the greatest number of proteins there has been demonstrated a broad band with a peak at about 280 rnp and a minimum, on the short wave-length side, at about 250 m,u (1). From quantitative studies of simple proteins, this band could be correlated with the presence of tyrosine, tryptophan, and phenylalanine (...
متن کاملThe Structure of the Ultraviolet Absorption Spectra of Certain Proteins and Amino Acids
1. The absorption spectra of a number of proteins in the region 2500 to 3000 A. have been found to comprise from six to nine narrow bands. In consequence of variation in the relative intensity of these bands from protein to protein, the absorption curve has a characteristic configuration for each protein. 2. These bands correspond closely in position with the narrow bands which appear in the ab...
متن کاملThe Effect of Hydrolysis of Proteins on their Ultraviolet - Absorption Spectra near 210 m , u
Proteins show a region of intense absorption at wavelengths shorter than 230 m,u that was first extensively investigated by Goldfarb, Saidel & Mosovitch (1951), who concluded that a large part of the absorption was due to the peptide bond. The only other major contribution came from the aromatic amino acid residues. Since proteins generally have similar peptidebond contents, it is to be expecte...
متن کاملAbsorption Spectra of Phytochrome Intermediates
Native phytochrome (124kdalton) was isolated from etiolated seedlings o f Avena sativa L. cv. Pirol (Baywa, Munich). From low temperature spectra (0 °C to — 165°C ) o f phytochrom e samples irradiated either with red or far-red light, spectra o f intermediates were calculated. Both absorption bands o f the phytochrome chromophore were reported. On the pathway P r i V r , native phytochrome does...
