Influence of methionine supplementation of growing diets enriched with lysine on feedlot performance and characteristics of digestion in Holstein steer calves. [PDF]
ObjectiveTwo trials were conducted in order to examine the effects of level of supplemental methionine on productive performance, dietary energetic, plasma amino acid concentration, and digestive function.MethodsDietary treatments consisted of a steam ...

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

New aspects of amino acid metabolism in cancer
An abundant supply of amino acids is important for cancers to sustain their proliferative drive. Alongside their direct role as substrates for protein synthesis, they can have roles in energy generation, driving the synthesis of nucleosides and ...

Cloning and sequence analysis of cDNAs encoding the cytosolic precursors of subunits GapA and GapB of chloroplast glyceraldehyde-3-phosphate dehydrogenase from pea and spinach [PDF]
Chloroplast glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is composed of two different subunits, GapA and GapB. cDNA clones containing the entire coding sequences of the cytosolic precursors for GapA from pea and for GapB from pea and spinach have ...

Research Progress of Amino Acid Metabolism PET Imaging in Tumor
Amino acid metabolism PET imaging plays a very important role in metabolism molecular imaging. Amino acid PET tracers include [1-11C]amino acid, labeling α-C amino acid, labeling side-chain amino acid, and N-substituted labeling amino acid.

Amino acid neurotransmitters in the CNS
D‐Aspartate exchange, defined as amino acid‐stimulated D‐[3H]aspartate efflux, was investigated in a preparation of rat brain synaptosomes. The efflux of radiolabelled D‐aspartate was found to be enhanced by micromolar concentrations of externally added D‐ and L‐aspartate, L‐glutamate, L‐cysteate.and L‐cysteinesulphinate.

Further characterization of glycine-containing microcystins from the McMurdo Dry Valleys of Antarctica [PDF]
Microcystins are hepatotoxic cyclic peptides produced by several cyanobacterial genera worldwide. In 2008, our research group identified eight new glycine-containing microcystin congeners in two hydro-terrestrial mat samples from the McMurdo Dry Valleys ...

Mechanisms and kinetic assays of aminoacyl‐tRNA synthetases
Accurate protein synthesis is crucial for life. The key players are aminoacyl‐tRNA synthetases (AARSs), which read the genetic code by pairing cognate amino acids and tRNAs. AARSs establish high amino acid selectivity by employing physicochemical limits in molecular recognition.
