Effect of cattle breed on muscle protein quality

open access: yesCzech Journal of Animal Science
The aim of the study was to compare the muscle protein quality in the m. longissimus, pars thoracis of bulls of the Aberdeen Angus (AA) and Czech Fleckvieh (CF) breeds reared under identical conditions within an extensive pasture-based system.

Chemically Fuelled Deracemization of Amino Acids [PDF]

open access: yes, 2022
openSystems that work out-of-equilibrium are common in nature, living organisms are the most striking example of that. Chemists are trying to mimic living organisms because of the multitude of properties that might be implemented in synthetic systems ...

Discerning protein pools by selective staining with self‐labeling tags

open access: yesFEBS Letters, EarlyView.
Cell surface proteins have an intra‐ and extracellular pool. Combining genetic fusion to self‐labeling tags that can be addressed with small molecule fluorophores allows separating these pools. We highlight recent developments and techniques for state‐of‐the‐art interrogation of cell surface proteins in the complex tissue setting.

Amino Acid Composition of Tamarind Fruit Growing Wild in Oyo Town

open access: yesFountain Journal of Natural and Applied Sciences (FUJNAS), 2013
Tamarind ( Tamarindus indica L.) fruit grows wild in some parts of the savannah region of Nigeria. The fruit is grossly underutilised in Nigeria, despite its invaluable contribution to the food security and economy of some Asian countries.

The Role of Proline and Certain Non-Essential Amino Acids in Chick Nutrition

open access: yesPoultry Science, 1962
Abstract THE relative abundance of serine, alanine, aspartic acid and proline in natural proteins has made it difficult to determine their role in chick nutrition when diets containing intact proteins are employed. The dispensable nature of these amino acids in a crystalline amino acid diet was reported by Almquist and Grau (1944).

Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

open access: yesFEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

Synthesis of potentially bioactive PABA-related N-(aminoalkyl)lactamic amino acids and esters via selective SNAr reactions

open access: yes, 2015
Potentially bioactive N-(aminoalkyl)lactamic amino acids and esters were synthesized in satisfactory to good yields by SNAr reactions of aromatic acids with N-(3-aminopropyl)lactams followed by esterification with tertiary amino alcohols.

The AAP gene family for amino acid permeases contributes to development of the cyst nematode Heterodera schachtii in roots of Arabidopsis [PDF]

open access: yes, 2013
The beet cyst nematode Heterodera schachtii is able to infect Arabidopsis plants and induce feeding sites in the root. These syncytia are the only source of nutrients for the nematodes throughout their life and are a nutrient sink for the host plant.

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

open access: yesFEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...

A whole food, plant-based diet reduces amino acid levels in patients with metastatic breast cancer

open access: yesCancer & Metabolism
Background Amino acids are critical to tumor survival. Tumors can acquire amino acids from the surrounding microenvironment, including the serum. Limiting dietary amino acids is suggested to influence their serum levels.
