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 کاملThe Distribution of I-131-labelled Parotin into the Muscle Tissue of Normal and Ovariectomized Guinea Pig Sensitized with Parotin.
As a part of physiochemical studies on muscular contraction, the authors have tried to follow up the distribution of antigenic protein into the muscular tissues of the guinea pig, as for anaphylactic contraction mechanism of uterus in guinea pig. To study the possible role of antigen-antibody reaction and estrogen or gestagen on the process, experiments were carried out on sensitized and non-se...
متن کاملEndocrinol. Jap., Vol.1, No.1(1954). BIOCHEMICAL STUDIES ON SALIVARY GLAND HORMONE
In order to prove the validity of the'salivary gland endocrine theory' proposed by Dr. T. Ogata(Tokyo University)la), the author and his collaborators have engaged in this study for approximately 15 years. In 1944, the author and his associates succeeded in isolating a crude protein from the bovine parotid gland which remarkably promoted the calcification of teeth and reduced the calcium level ...
متن کامل[The effects of parotin components on testosterone biosynthesis in rats].
During our studies on the active moiety of parotin, we succeeded in purifying MP-parotin (MW = 130000) and parotin-subunit (MW = 45000) from crude parotin. Furthermore, AA-1 (MW = 9100) was isolated after the tryptic cleavage of the parotin-subunit. AA-1 was the smallest unit ever obtained which had serum Ca-decreasing activity and circulating leucocyte-increasing activity together with the nat...
متن کاملStudies on the salivary gland hormones labeled with I 131. 4. Studies on the degradation of I 131 labeled parotin by several tissue homogenates of rat.
Recently it was reported from this laboratory as one of a series of studies on the Salivary Gland Hormones, that liver and spleen were the main and characteristic sites of localization of radioactivity after administration of I 131 labeled Parotin to rats(Tanaka and Ito, 1958). And subsequently it was also observed that this characteristic localization of radioactivity in the liver and spleen a...
