A pore smaller than one nanometer reads peptide sequences amino acid by amino acid, pinpointing single-site Alzheimer's ...

Elongation, a crucial step in the translation process of protein synthesis, gets disrupted by amino acid sequences with an abundance of N-terminal aspartic and glutamic acid residues in eukaryotic ...

Protein sequencing presents different challenges than nucleic acid sequencing, meaning that proteomics has yet to benefit as much as genomics from the next-generation sequencing revolution. However, ...

An amino acid that shows up preferentially in ancient sequences was likely incorporated early on. Conversely, LUCA's sequences are depleted for amino acids that were recruited later but became ...
