Disulfide bridges formed between cysteine residues in peptides and proteins are fundamental building blocks for the molecular architecture and, thus, can govern basic biological processes. The formation of a disulfide bond by two side chain Sγ atoms of spatially proximal cysteines constitutes a two-electron … Se mer To emphasize the special role of cysteines as a structure-forming or catalytic unit in the context of an evolutionary process, we present a short analysis … Se mer Structurally, the disulfide linkage in a cystine displays a typical bond length of ~2.04 Å (Chaney and Steinrauf, 1974). The chirality of the disulfide linkage is a stereo-electronic consequence of the four free electron pairs on … Se mer From earlier studies it is known that protease inhibitors, e.g., the thrombin inhibitors rhodniin (Van De Locht et al., 1995) and dipetalin (Icke et al., 2002), are composed of (repetitive) Kazal-type domains structurally … Se mer Conotoxins, small disulfide bridge-containing peptides found in marine cone snails, have attracted considerable scientific interest as … Se mer NettetAmong the insulin-family peptides, two additional cysteine residues other than six conserved cysteines are sometimes found in invertebrate insulin-like peptides ... おびし荘 チェックイン
