Chemical ligation
WebThe sulfonamide–zinc ion interaction, performing a key role in various biological contexts, is the focus of the present study, with the aim of elucidating ligation motifs in zinc complexes of sulfa drugs, namely sulfadiazine (SDZ) and sulfathiazole (STZ), in a perturbation-free environment. To this end, an approach is exploited based on mass spectrometry coupled … WebChemical Synthesis of Full-Length α-Bungarotoxin Our initial aim was to assemble the linear α-BgTx peptide starting from the N- to the C-terminus by ligating PA-α-BgTx 1-28 ( 1) with α-BgTx 29-43 ( 3) to obtain PA-α-BgTx 1-43 ( 6 ), followed by PA-α-BgTx 1-43 ligation with α-BgTx 44-74 ( Figure 1 A).

WebProtein synthesis is a non-trivial task involving many chemical steps, and these steps increase with the size of the protein. Therefore, larger proteins are difficult to synthesize with high yield. We have developed a strategy which we term hybrid-phase native chemical ligation (NCL) to overcome some of the limitations of size and yield. WebFeb 21, 2024 · Protein ligation, in which two or more polypeptides are covalently linked, is a powerful strategy for generating semisynthetic products and for controlling polypeptide …
