Protein Variety and Complete Amino Acids 🥗🍗
Understanding protein variety is crucial because muscles aren’t built from protein alone, they’re built from the building blocks of protein: amino acids.
🥩 Different Proteins = Different Amino Acid Profiles

🥦 Amino Acid Synergy: Beyond Protein Intake 🥗
Muscle protein synthesis (MPS) depends on a full spectrum of essential amino acids (EAAs), not just a high protein intake.
💪🔺 Leucine as the Anabolic Trigger
3️⃣ BCAA Triad: Leucine, Isoleucine, and Valine
💪🔧 EAA Completeness for Muscle Repair
⏱️📊 Timing and Ratios Matter

Understanding Protein Quality 🍖🥦
Muscle growth occurs when protein synthesis exceeds breakdown. High-quality proteins provide the essential amino acids (EAAs), especially leucine, to stimulate MPS effectively.

We identified protein domains in LUCA (#LastUniversalCommonAncestor). Their distinctive #AminoAcid usage reveals the order amino acids were added to the #GeneticCode, based mostly on size. Older proteins hint at earlier alternative codes. 1/15 https://www.pnas.org/doi/10.1073/pnas.2410311121 #astrobiology #phylostratigraphy #sulfur #metalloproteins
🍖 Protein Quality and Digestibility in Muscle Building
🥗 Amino Acid Profile
Proteins with a complete amino acid profile—meaning they contain all nine essential amino acids—are crucial for muscle building. Animal-based proteins (like chicken, fish, and eggs) and some plant-based options (like quinoa and soy) offer complete profiles, supporting optimal muscle protein synthesis.

2 #aminoacid residues in N-terminal region of #polymerase acidic protein determine #virulence of Eurasian avian-like #H1N1 swine #influenza viruses in mice, J Virol.: https://journals.asm.org/doi/full/10.1128/jvi.01293-24?af=R
We identified that 2 naturally occurring aa mutations in PA derived from #H1N1/2009 are crucial determinants of virulence of rEA H1N1 viruses & revealed differential mechanism by which these 2 mutations affect transcription & replication of vRNA.
#Genetic & #molecular characterization of #H9N2 avian #influenza viruses in #Yunnan Province, SW #China, Poul Sci.: https://www.sciencedirect.com/science/article/pii/S0032579124006199?via%3Dihub
Analysis of these #aminoacid sites suggests that H9N2 influenza viruses in Yunnan continue to mutate and adapt to #mammals & are sensitive to #neuraminidase #inhibitors but resistant to #adamantanes. It is necessary to strengthen surveillance of AIV H9N2 subtypes in poultry and LPMs in Yunnan to further understand their genetic diversity.
#Aminoacid #mutations #PB1-V719M and #PA-N444D combined with #PB2-627K contribute to the #pathogenicity of #H7N9 in #mice, Vet Res.: https://veterinaryresearch.biomedcentral.com/articles/10.1186/s13567-024-01342-6
Overall, this study revealed that #virulence in H7N9 is a #polygenic trait and identified novel virulence-related residues (PB2-627K combined with PB1-719M and/or PA-444D) in viral ribonucleoprotein (vRNP) complexes.

Amino Acid Tryptophan Detected in Young Star Cluster
Using infrared spectral data from NASA’s Spitzer Space Telescope, Instituto de Astrofísica de Canarias astronomer has detected the aromatic amino acid tryptophan in the interstellar gas of the young star cluster IC 348. This could be an indication that the molecule is widespread in interstellar space.

Our preprint describes how #EffectivePopulationSize affects #AminoAcid usage. https://www.biorxiv.org/content/10.1101/2023.02.01.526552v2. Within highly exchangeable pairs of amino acids, high Ne species are able to prefer #arginine over #lysine, and #valine over #isoleucine. This matches #thermophile preferences, as expected from theories of marginal protein stability at mutation-selection-drift balance. 1/6
