Metabolism of amino acid amides in Pseudomonas putida ATCC 12633 [PDF]

open access: yes, 1993
The metabolism of the natural amino acid L-valine, the unnatural amino acids D-valine, and D-, L-phenylglycine (D-, L-PG), and the unnatural amino acid amides D-, L-phenylglycine amide (D, L-PG-NH2) and L-valine amide (L-Val-NH2) was studied in ...

The Regulatory Role of MeAIB in Protein Metabolism and the mTOR Signaling Pathway in Porcine Enterocytes. [PDF]

open access: yes, 2018
Amino acid transporters play an important role in cell growth and metabolism. MeAIB, a transporter-selective substrate, often represses the adaptive regulation of sodium-coupled neutral amino acid transporter 2 (SNAT2), which may act as a receptor and ...

White adipose tissue urea cycle activity is not affected by one-month treatment with a hyperlipidic diet in female rats. [PDF]

open access: yes, 2016
Under high-energy diets, amino acid N is difficult to dispose of, as a consequence of the availability of alternative substrates. We found, recently, that WAT contains a complete functional urea cycle, we analyzed the possible overall changes in the WAT ...

Atherosclerosis Linked to Aberrant Amino Acid Metabolism and Immunosuppressive Amino Acid Catabolizing Enzymes

open access: yesFrontiers in Immunology, 2020
Cardiovascular disease is the leading global health concern and responsible for more deaths worldwide than any other type of disorder. Atherosclerosis is a chronic inflammatory disease in the arterial wall, which underpins several types of cardiovascular

Gut amino acid absorption in humans: Concepts and relevance for postprandial metabolism

open access: yesClinical Nutrition Open Science, 2021
Summary: Dietary amino acid absorption kinetics are an important determinant of protein quality. The term “amino acid digestibility” is commonly used to refer to the amount of ingested amino acids that become available following absorption.

Inducible arginase 1 deficiency in mice leads to hyperargininemia and altered amino acid metabolism [PDF]

open access: yes, 2013
Arginase deficiency is a rare autosomal recessive disorder resulting from a loss of the liver arginase isoform, arginase 1 (ARG1), which is the final step in the urea cycle for detoxifying ammonia. ARG1 deficiency leads to hyperargininemia, characterized

Amino acid metabolism in primary bone sarcomas

open access: yesFrontiers in Oncology, 2022
Primary bone sarcomas, including osteosarcoma (OS) and Ewing sarcoma (ES), are aggressive tumors with peak incidence in childhood and adolescence. The intense standard treatment for these patients consists of combined surgery and/or radiation and maximal

Amino acid metabolism conflicts with protein diversity [PDF]

open access: yes, 2014
The twenty protein coding amino acids are found in proteomes with different relative abundances. The most abundant amino acid, leucine, is nearly an order of magnitude more prevalent than the least abundant amino acid, cysteine.

Fractionation, molecular composition, and biological effects of organic matter in bio-stabilization sludge with implication to land utilization

open access: yesEnvironment International, 2022
Bioactive organic compounds (BOCs) contained in bio-stabilized products of waste activated sludge (WAS) have attracted considerable attention, as they can enhance the fertilizing effect of WAS in land applications.
