WebIn this study we used cysteine-scanning mutagenesis and modification (SCAM) to screen >50 residues in the intracellular vestibule of ClC-0. We identified 14 positions sensitive to the negatively charged thiol-modifying reagents sodium (2-sulfonatoethyl)methanethiosulfonate (MTSES) or sodium 4-acetamido-4'-maleimidylstilbene-2'2-disulfonic acid ... WebCysteine is the most widely used type of reactivity-based probe. Cysteine reactive probes commonly carry the iodoacetamide group. 24 Iodoacetamide alkyne probes were initially developed so that biotin tags could be conjugated to probe-modified proteins via click chemistry for subsequent enrichment and identification 20 (Fig. 5.1A).Isotopic reagents …

A beta turn is a turn in the primary structure, stabilized by hydrogen bonding. Because Proline has an odd, cyclic structure, when it forms peptide bonds, it induces a bend into the amino acid chain. I challenge you to draw the peptide chain with proline; you will see it.
