Substrate specificity of tonin from rat submaxillary gland.
The substrate specificity of tonin from rat submaxillary gland was examined with a series of synthetic peptides encompassing the C-terminus of the decapeptide substrate angiotensin I. In contrast to angiotensin I-converting enzyme from plasma or lung, only angiotensin I, (des-Asp1)-angiotensin I, and (des-Asp1, des-Arg2)-angiotensin I are substrates of tonin with Km values of 34.5 muM, 39.3 muM...
متن کاملSubstrate stabilization of the palmitoyl-coenzyme A hydrolase activity of rat submaxillary gland.
The long-chain acyl-CoA hydrolase (EC 3.1.2.2) activity of rat submaxillary salivary gland, found in the postmicrosomal supernatant fraction, has a pH optimum of 7.4. This hydrolase activity was found to be extremely labile, but inclusion of glycerol or the substrate palmitoyl-CoA in the preparations markedly stabilized the activity. Gel-filtration studies revealed multiple forms of the hydrola...
متن کاملPaper Electrophoretic Study of a Rat Submaxillary Gland Extract †
A number of physico-chemical studies on the secretory products of salivary glands have been reported, but only a few scattered data appear available concerning constituents of the total salivary gland. In regard to electrophoresis, very few studies exist pertaining to any salivary gland protein components. Phase boundary electrophoresis studies on mucin extracts from animal salivary glands have...
متن کاملIn vitro secretion of immunoreactive tonin from dispersed rat submandibular gland cells.
Dispersed cells from the submandibular gland of the male rat were prepared by collagenase treatment to study the mechanism by which immunoreactive tonin is secreted in vitro. Norepinephrine, epinephrine, and phenylephrine stimulated tonin release, an effect that was inhibited by phentolamine but not by propranolol, whereas isoproterenol, carbachol, histamine, and serotonin did not stimulate ton...
متن کاملUnusual Peroxidase-positive Granules in the Developing Rat Submaxillary Gland
Unusual peroxidase-positive granules exist in a particular cell type in the rat submaxillary gland during the first 2 wk after birth . The granules display remarkable substructure and clearly show cytochemical evidence of endogenous peroxidase activity . The cells containing the peroxidase-positive granules comprise portions of the terminal end pieces, or so-called "terminal tubules" (4), in th...
