Evolution‐guided yeast complementation reveals functional differences in human PSPH variants

open access: yesFEBS Open Bio, EarlyView.
Ancient genomes can help guide which human genetic variants are tested experimentally. This study applies that idea to PSPH, a gene involved in serine biosynthesis, and uses high‐throughput yeast complementation to compare variant function. The findings reveal measurable differences among selected alleles and illustrate the value of evolution‐guided ...

Response surfaces showing the relationship between nitrogen corrected apparent metabolisable energy (AMEn) and dietary digestible branched chain amino acids in male broilers from 24 to 28 days post-hatch where the maximum AMEn (12.42 MJ/kg) could be estimated at 15.74 g/kg digestible leucine.

Avidin is evolutionarily conserved in fish but dispensable for development and resistance against Streptococcus agalactiae in zebrafish

open access: yesFEBS Open Bio, EarlyView.
The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

Amino-acids in soil

open access: yes, 1950
ALTHOUGH the protein nature of at least one-third of the organic nitrogen of soil has been established, very little is known of the amino-acid composition of this protein material. The isolation of amino-acids from soil hydrolysates is rendered difficult

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

open access: yesFEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

True ileal amino acid digestibility and digestible amino acid scores (DIAASs) of the cruciferin and napin fractions of rapeseed: Impact of processing

open access: yesFood Chemistry
Processes are being developed to exploit proteins from the residue of rapeseed oil extraction. Two main fractions of proteins can be purified: cruciferin and napin. The present work was carried out to characterize the nutritional quality of these fractions, while exploring the effect of the extraction conditions (neutral or acid), and that of the post ...

Dietary Formulation with Cottonseed Meal on a Total Amino Acid Versus a Digestible Amino Acid Basis

open access: yesPoultry Science, 1995
The results of previous experiments indicated that performance of chicks fed corn-cottonseed meal (CSM) diets was inferior to performance of chicks fed a corn-soybean meal (SBM) diet and that true digestibilities of amino acids (AA) in CSM were lower than those in SBM.

The C‐terminal domain of yeast Arginyltransferase1 is essential for its catalytic activity

open access: yesFEBS Open Bio, EarlyView.
Arginyltransferase 1 (Ate1), a eukaryotic enzyme, catalyses arginylation, transferring arginine from tRNA‐Arg to the amino terminus of the target protein. Overexpression of Ate1 in yeast is lethal and is dependent on arginylation. This study elucidates how mutations in the cofactor‐binding and active site of Ate1 and truncation of its structural ...

Digestible lysine/digestible protein ratio in diets for Nile tilapia [PDF]

open access: yes, 2009
Este estudo foi realizado para determinar a melhor relação lisina digestível:proteína digestível em rações para juvenis de tilápia-do-nilo. As tilápias (11,0 ± 0,43 g) foram distribuídas em 36 aquários (250 litros) numa densidade de seis peixes ...
