N- and C-terminal amino acids of saliva parotin A.
During the course of an investigation into the biological activities and chemical properties of saliva parotin A it became necessary to study the chemical structure of this protein. Previous workers have reported that the molecular weight of saliva parotin A prepared from human saliva is 15,900 (Ito, Y. 1960). Proline, threonine, aspartic acid, and gluta mic acid are contained in saliva parotin...
متن کاملTerminal amino acids of rhodopsin.
Rhodopsin, the photosensitive pigment of rod vision, is a chromoprotein composed in equimolar parts of the protein opsin and the carotenoid retinene (1). Its absorption spectrum and molar extinction are known (2) and the kinetics of bleaching by light and of regeneration have been investigated (3). An upper limit of 40,000 has been set for its molecular weight (cattle) (1). Since rhodopsin is i...

متن کاملThe Terminal Amino Acids of Wheat Gliadin
Wheat gliadin has been found by two different methods to contain three N-terminal histidine residues for each molecular weight of 27,000. Trace amounts of N-terminal aspartic acid, glutamic acid, alanine, valine, and serine were also detected in the preparation used. Hydrolysis in boiling hydrochloric acid partially destroyed the di-2,4-dinitrophenyl derivative of histidine. Losses of from 5% t...
متن کاملPerformance of 2-Amino Tetraphenyl Porphyrin as Stationary Phase in RP-HPLC of Amino Acids
The search for new stationary phases has been one of the predominant concerns in high performance liquid chromatography (HPLC) in order to achieve better resolutions, longer column lives, and reduce the time of analysis. A chromatographic packing for separation of underivatized amino acids (AAs) were prepared by dynamically coating 2-amino tetraphenyl prophyrin (atpp) on a C-18 reversed-pha...
