WebThe β-amyloid precursor protein (APP), which is a key player in Alzheimer's disease, was recently reported to possess an Fe(II) binding site within its E2 domain which exhibits ferroxidase activity [Duce et al. 2010, Cell 142: 857]. WebHowever, breakdown rates of microinjected 125I-labeled lysozyme-S-peptide and 125I-labeled insulin A chain-S-peptide conjugates were increased 2-fold during serum deprivation. We suggest that RNase S-peptide acts as a "single sequence" that directs cytosolic proteins to lysosomes through a pathway that is activated by deprivation …

WebPeptide mass mapping is a technique that uses powerful search engines (e.g. Mascot) to identify a protein from mass spectrometry data and primary sequence databases. The general approach is to take a small sample of the protein and digest it with a proteolytic enzyme, such as trypsin. Trypsin cleaves the protein after lysine and arginine residues. tim hortons tim cardsWeb26 jan. 2024 · Polypeptide structure can be the same as the primary or secondary structures of proteins but has fewer amino acids per chain. The number of amino acids they contain means they are not officially referred to as proteins but as polypeptides.
