WebJan 29, 2024 · Abstract. Enzyme-catalyzed proximity labeling (PL) combined with mass spectrometry (MS) has emerged as a revolutionary approach to reveal the protein-protein interaction networks, dissect complex biological processes, and characterize the subcellular proteome in a more physiological setting than before. The enzymatic tags are being … WebJan 13, 2024 · The cells were labeled with biotin-XX-phenol (BxxP) and were harvested in urea lysis buffer followed by protein digestion and BioSITe-based enrichment of biotinylated peptides as described earlier. The raw data was searched using Sequest search algorithm against mouse RefSeq protein database containing appropriate BirA-p190 and BirA-p210 ...

WebAug 23, 2024 · Biotin-phenol is oxidized by the peroxidase into phenoxyl radical which in turn reacts with neighboring proteins at their electron-rich side chains. Because the half-life of the phenoxyl radical is less than 1 ms, the intensity of labeling falls dramatically within few nanometers from the active site of the peroxidase. optics co. ltd
