Amino acids induce peptide uptake via accelerated degradation of CUP9, the transcriptional repressor of the PTR2 peptide transporter [PDF]

, 2008
Multiple pathways link expression of PTR2, the transporter of di- and tripeptides in the yeast Saccharomyces cerevisiae, to the availability and quality of nitrogen sources.

Alterations in serum amino acid concentrations in dogs with protein-losing enteropathy [PDF]

, 2018
BackgroundCertain amino acids are decreased in humans with inflammatory bowel disease (IBD) and supplementation with the same amino acids has shown beneficial effects in animal models of IBD.

Branched Chain Amino Acids: Beyond Nutrition Metabolism

International Journal of Molecular Sciences, 2018
Branched chain amino acids (BCAAs), including leucine (Leu), isoleucine (Ile), and valine (Val), play critical roles in the regulation of energy homeostasis, nutrition metabolism, gut health, immunity and disease in humans and animals.

Different domains cooperate to target the human ribosomal L7a protein to the nucleus and to the nucleoli. [PDF]

, 1997
The human ribosomal protein L7a is a component of the major ribosomal subunit. We transiently expressed in HeLa cells L7a-β-galactosidase fusion proteins and studied their subcellular localization by indirect immunofluorescence staining with anti-β ...

Ragulator-Rag complex targets mTORC1 to the lysosomal surface and is necessary for its activation by amino acids.

Cell, 2010
The mTORC1 kinase promotes growth in response to growth factors, energy levels, and amino acids, and its activity is often deregulated in disease.

Amino acids: inhibitors or promoters of anaerobic biocorrosion of steels? [PDF]

, 2007
Various authors have shown that some amino acids can act as corrosion inhibitors, which has generated an increasing interest in these compounds as substitutes to conventional corrosion inhibitors that are usually toxic [1,2].

Amino acid disorders [PDF]

Annals of Translational Medicine, 2018
Amino acids serve as key building blocks and as an energy source for cell repair, survival, regeneration and growth. Each amino acid has an amino group, a carboxylic acid, and a unique carbon structure. Human utilize 21 different amino acids; most of these can be synthesized endogenously, but 9 are "essential" in that they must be ingested in the diet.

A thermodynamic basis for prebiotic amino acid synthesis and the nature of the first genetic code

, 2009
Of the twenty amino acids used in proteins, ten were formed in Miller's atmospheric discharge experiments. The two other major proposed sources of prebiotic amino acid synthesis include formation in hydrothermal vents and delivery to Earth via meteorites.

Puromycin Sensitivity of Ribosomal Label after Incorporation of 14C-Labelled Amino Acids into Isolated Mitochondria from Neurospora crassa [PDF]

, 1969
Radioactive amino acids were incorporated into isolated mitochondria from Neurospora crassa. Then the mitochondrial ribosomes were isolated and submitted to density gradient centrifugation. A preferential labelling of polysomes was observed.
