Peptide-bound methionine as methionine sources for protein accretion and cell proliferation in primary cultures of ovine skeletal muscle.
Ruminants have high concentrations of peptide-bound amino acids in the circulation. Earlier studies in our laboratory showed that a myogenic cell line (C2C12) developed from mouse skeletal muscle and a mammary epithelial cell line (MAC-T) developed from bovine mammary epithelial tissues are able to utilize peptides as amino acid sources. In this study, primary cultures of ovine myogenic satelli...
متن کاملEthylene production from peptides and protein containing methionine.
It has been reported that the C0-C4 carbons of methionine are converted to ethylene in FMN-light (23) and Cu"!-ascorbate (10) model systems. Yang (22) has shown that C-C, carbons of 2-keto-4-methylthiobutyrate and the Cr, carbons of 3-methylthiopropionaldehyde (i.e., methional) are converted to ethylene in a model peroxidase system. When methionine was fed to apple tissue, the C-C4 carbons were...
متن کاملEfficacy of DL-methionine hydroxy analog free acid and DL-methionine as methionine sources for pigs.
Two experiments were conducted to evaluate the efficacy of dietary DL-methionine hydroxy analog-free acid (MHA-FA, 88%) compared with DL-methionine (DLM, 99%) as Met sources in pigs. In Exp. 1, a total of 245 crossbred pigs (initial BW of 6.4 kg [SD = 0.5]) were allotted to 7 treatments in 7 replicates for an experimental period of 28 d. The basal diet (BD) was formulated to contain 17.5% CP an...
متن کاملUtilization of methionine-containing peptides and their derivatives by a methionine-requiring auxotroph of Saccharomyces cerevisiae.
A number of peptides containing methionine and glycine, such as Met-Met-Gly, Met-Met-Gly-Met, and Met-MetGly-Gly, were synthesized by conventional techniques. The growth response of Saccharomyces cerevisiae G1333, a methionine-requiring auxotroph, toward various di, tri, and tetrapeptides containing methionine was measured. The yeast mutant utilized and contained peptidase activity toward most ...
متن کاملMethionine Requirement and Commercial Methionine Sources in Growing Pigs
Methionine is a limiting amino acid in commercial swine diets and commonly supplemented as dry DL-methionine (DL-Met, 99%) or as liquid DL-methionine hydroxy analogue-free acid (liquid MHA-FA, containing 88% of active substance). New and intriguing research has been published in poultry and swine as to what is the nutritional effectiveness of liquid MHA-FA relative to DLMet, and what are the re...
