Understanding protein non-folding

WebMay 8, 2024 · Templated folding of IDPs. Despite the considerable interest in understanding the properties and peculiarities of IDPs, our current understanding of the mechanisms whereby binding-induced folding takes place is still relatively limited and based on the study of small protein systems. WebTo understand how a protein gets its final shape or conformation, we need to understand the four levels of protein structure: primary, secondary, tertiary, and quaternary. Primary structure The simplest level of protein structure, primary structure, is simply the sequence …
