Optical tweezers protein folding
WebNov 27, 2024 · Over the past decade, optical tweezers (OT) have been increasingly used in neuroscience for studies of molecules and neuronal dynamics, as well as for the study of model organisms as a whole. ... OT can be used to measure piconewton and femtonewton scale forces, such as those encountered protein folding (Bustamante et al., 2024) or cell ... WebWhile much work is being done in the design of thermodynamically stable proteins, the folding process of artificially designed proteins is not well-studied. Here we used single-molecule force spectroscopy by optical tweezers to study the folding of ROSS, a de-novo designed 2x2 Rossmann fold.
