amino acid analogs with extended carbon chains (γ-, δ-, ε-, and ζ-) or cyclic structures (cyclobutane, cyclopentane, and cyclohexane) to improve tRNA charging. We then demonstrate site-specific incorporation of these non-canonical, backbone-extended monomers at the N- and C- terminus of ...
8), the side chains of conserved amino acids make salt bridges with the bound fatty acid, essentially locking the carboxyl in place. Using the structure of HAS-18:0 (PDB ID 1e7i) as a template, we modeled bound configurations of C26:0 into these five sites. In each case, we ...
The side chains of the amino acids defining the hydrophobic contacts most relevant for the folding of the peptide are highlighted in light blue. The secondary structure elements were defined using the programs STRIDE74 and DSSP75. reduction of R1 values appears constant along the entire peptide ...
This bottlebrush consists of multiple PEG chains covalently linked to a central chain, creating a stronger peptide protective shield than linear monoPEGylation. In this case, the PEG bottlebrush increased peptide half-life after intravenous administration to immunocompetent mice since it prevented its ...
RNA isoforms influence cell identity and function. However, a comprehensive brain isoform map was lacking. We analyze single-cell RNA isoforms across brain regions, cell subtypes, developmental time points and species. For 72% of genes, full-length isofo
In most, if not all, eukaryotes and certain bacteria, sphingolipids are present with acyl chains hydroxylated at position 2. Though 2-hydroxylated sphingolipids are present throughout various organs and cell types, their concentration peaks in myelin and skin. The involvement of the enzyme fatty ...
Besides diannexin, the blood half-life of anxA5 has 13 5 44 Apoptosis (2021) 26:534–547 been extended to about 5 h in mice by chemically coupling multiple PEG chains via the amine groups of anxA5 [52]. This approach includes the risk of substantial deactiva- tion of the anxA5 ...
Such behaviour has in fact been reported for proteins carrying net negative charge42,47, for example, the negatively charged wild-type yeast protein Sup35 which carries a net excess of six acidic amino acids (aspartic and glutamic acids) over the number of basic side chains (lysine and ...
