Sodium-potassium dependent inorganic 35S-sulfate incorporation into cornea.
T, .ranscorneal potentials have been reported by several laboratories and have been related to an active transfer of sodium ions across the cornea. Both epithelial and endothelial cells have been implicated as sites of a metabolic pump. The active transport of ions across the cornea is involved in the maintenance of hydration, thickness, and transparency." The effect of these ions may be indire...
متن کاملThe preparation of [35S]homocysteine thiolactone free of [35S]methionine.
The unambiguous study of homocysteine metabolism requires a source of [355]homocysteine completely free from contaminating [35S]methionine. Until now, such a reagent has not been readily available. Homocysteine is an important metabolite involved in methionine, cysteine and methylation metabolism. Homocysteine can be methylated to form methionine with either 5-methyltetrahydrofolate [1] or beta...
متن کامل35S-methionine incorporation in rat lenses in media simulating cataractogenic conditions.
Lenses obtained from rats on a galactose diet for six days showed a marked reduction in their capacity to incorporate 35S-methionine into protein even though there was no reduction in the capacity of the lenses to incorporate 3H-thymidine and 3H-uridine into DNA and RNA, respectively. Therefore, lenses were incubated in media in which various putative cataractogenic factors were varied to deter...
متن کاملIncorporation of L-methionine-methyl-14C into gentamicins.
Gentamicin C complex, produced by Micromonospora purpurea1*2), is composed of three components, Cla, C2 and Q (Fig. 1). These components are methylaminoglycosides, which are distinct from other related antibiotics such as the kanamycins, neomycinsand paromomycins. As seen in Fig. 1, gentamicins Cla, C2, and Q possess one C-methyl and one N-methyl group, two C-methyl and one N-methyl groups and ...
متن کاملThe incorporation of labeled methionine into protein by pituitary tissue.
In recent years numerous reports on the uptake of labeled amino acids by the proteins of tissue preparations have appeared. Various amino acids have been used, and the reaction has been shown to occur in tissue slices (l-4), homogenates (5), and in resting bacteria (6, 7). Considerable evidence has accumulated, indicating that this labeling of protein represents a synthesis of peptide bonds. In...
