cysteine, and tyrosine), and are less sensitive to amino acid imbalances and antagonisms. Throughout adulthood, cats and dogs may lose 34% and 21% of their lean body mass, respectively. Adequate intakes of high-quality protein (i.e., 32% and 40% animal protein in diets of aging dogs a...
amino acid transporter with a preference for small hydrophobic and polar amino acids (Fig.4a). It was surprising, given the high sequence identity to the CATs, that GkApcT showed poor recognition of the cationic amino acidsl-arginine andl-lysine. Analysis of the binding site in GkApcT ...
Cats also require one extra amino acid-like compound, called taurine.Taurineis found naturally in animal-based ingredients and is also available as a supplement. It is critical for a cat’s normal heart, eye, and reproductive function. Because it plays such a critical role for health, it is...

downregulate arginine synthesis, exogenous arginine supply is critical for tumors survival and proliferation. Arginine can be obtained through cationic amino acid transporter (CAT) family transporters, including CAT-1, CAT-2 and CAT-3. CATs are always upregulated in many human cancers [37]. Thus,...

5b; P<0.01, ANOVA, n=3), consistent with the TgNPT1-independent arginine uptake pathway(s) being able to transport a range of cationic amino acids, including arginine, lysine and ornithine. By contrast, the addition of 1?mM of the anionic amino acid glutamate or the neutral amino acid ...
Branched Chain Amino Acid Aminotransferase is an enzyme involved in the initial breakdown of branched chain amino acids (BCAAs) such as leucine, isoleucine, and valine into different products for energy production in nonhepatic tissues like muscle. ...
(eIF5A), whose expression/function is strongly correlated with unfavorable prognostic implications for several cancers73,74,75. The spermidine-derived amino acid hypusine, a unique eIF5A posttranslational modification of lysine residue 50, is essential for eIF5A functions76. Polyamines also exist as ...
Lysine Leucine Tryptophan Histidine Isoleucine Methionine Phenylalanine Threonine Valine Arginine is required for children but is typically not included in amino acid supplements because it is not an essential amino acid.
