Passage of radioactive amino acids through nonprotein fractions of hen oviduct during incorporation into protein.
The hen oviduct has been observed to lose virtually all its ability to incorporate free ammo acid into protein upon homogenation (2). In many instances, however, homogenation of a prelabeled mince, followed by removal of most of the radioactivity, and subsequent incubation, has led to a larger quantity of radioactivity contained in the protein fraction than was present at the start or early in ...
متن کاملIncorporation of nonnatural amino acids into proteins.
The genetic code is established by the aminoacylation of transfer RNA, reactions in which each amino acid is linked to its cognate tRNA that, in turn, harbors the nucleotide triplet (anticodon) specific to the amino acid. The accuracy of aminoacylation is essential for building and maintaining the universal tree of life. The ability to manipulate and expand the code holds promise for the develo...
متن کاملIncorporation of nitrogen into rumen bacterial fractions of steers given protein- and urea-containing diets. Ammonia assimilation into intracellular bacterial amino acids.
Experiments were carried out in vivo to investigate the pathways of ammonia incorporation into rumen bacteria, bacterial fractions and free amino acids within the bacteria. Steers were alternately given two isoenergetic, isonitrogenous diets containing the nitrogen mainly as either urea or decorticated groundnut meal (DCGM). At the end of each period on a given diet, a solution of 15NH4Cl was i...

L-Lysine was microencapsulated by the spray-dry met.hod for improvement of the balance of alllino acids in ruminants. The rumen-bypm;s lllicrocCljJsulc was jJrqmn~d using zein or shellac as an outer coat.ing agcnt [or protection against microbial degradation in the rumen. L-Lysine was generated with a .yield of ,')0% in casp of zein microcapsules and :3:3% in shellac microcapsules and a mean pa...
متن کاملNonprotein amino acids in the murchison meteorite.
Twelve nonprotein amino acids appear to be present in the Murchison meteorite. The identity of eight of them has been conclusively established as N-methylglycine, beta-alanine, 2-methylalanine, alpha-amino-n-butyric acid, beta-amino-n-butyric acid, gamma-amino-n-butyric acid, isovaline, and pipecolic acid. Tentative evidence is presented for the presence of N-methylalanine, N-ethylglycine, beta...
