Gustatory sensitivity to amino acids in bumblebee mouthparts

Royal Society Open Science
Bees rely on amino acids from nectar and pollen for essential physiological functions. While nectar typically contains low (less than 1 mM) amino acid concentrations, levels in pollen are higher but variable (10–200 mM).

Reduction in dietary lysine increases muscle free amino acids through changes in protein metabolism in chickens

Poultry Science, 2020
Taste is crucial to meat quality, and free Glu is an important taste-active component in meat. Our recent study showed that the short-term feeding of a low-Lys diet increases the concentration of free Glu and other free amino acids in chicken muscle and ...

Comparative analyses on medium optimization using one-factor-at-a-time, response surface methodology, and artificial neural network for lysine–methionine biosynthesis by Pediococcus pentosaceus RF-1

Biotechnology & Biotechnological Equipment, 2017
Optimization strategy that encompassed one-factor-at-a-time (OFAT), response surface methodology (RSM), and artificial neural network method was implemented during medium formulation with specific aim for lysine-methionine biosynthesis employing a newly ...

Effects of lysine and methionine in a low crude protein diet on the growth performance and gene expression of immunity genes in broilers

Poultry Science, 2020
Globally, the poultry industry is 1 of the most advanced livestock industries. Feed contributes to the biggest proportion (65–70%) of the production cost.

Assessment of Neurodegenerative Changes in Turkeys Fed Diets with Different Proportions of Arginine and Methionine Relative to Lysine

Animals, 2022
We postulated that the use of optimal levels and proportions of Arg and Met relative to a low or high concentration of Lys in diets for meat turkeys would reduce the occurrence of metabolic disturbances in the nervous tissue that can lead to ...

LSD1 is essential for oocyte meiotic progression by regulating CDC25B expression in mice [PDF]

, 2015
Mammalian oocytes are arrested at prophase I until puberty when hormonal signals induce the resumption of meiosis I and progression to meiosis II.

ON LYSINE AND ORNITHINE [PDF]

Journal of Biological Chemistry, 1942
SUMMARY It is shown that significant amounts of ornithine and lysine may be precipitated by silver nitrate and sodium hydroxide. The formation of phenylhydantoins from phenyl isocyanate derivatives of ornithine and lysine by the action of acid is shown to be accompanied by racemization.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Fertigation with Zn-Lysine Confers Better Photosynthetic Efficiency and Yield in Water Stressed Maize: Water Relations, Antioxidative Defense Mechanism and Nutrient Acquisition

Plants, 2022
Different strategies including the exogenous use of micronutrient-chelated amino acids are being employed for better crop yield with limited fresh water for irrigation. The present study was conducted to assess the effects of foliar-applied Zn-lysine (Zn-

Alpha-aminoadipic acid: A product of lysine metabolism [PDF]

, 1948
As part of a study of protein and peptide metabolism lysine was synthesized with C14 in the ε position and resolved into the L and D isomers. 10 mg. of labeled lysine dihydrochloride (either L- or D-) and 0.66 gm.
