Abstract:Classical Anfinsen′s dogma states that a protein folds into a single unique conformation with minimal Gibbs energy under physiological conditions. However, recent advances have revealed that single amino acid sequences can fold into two or more conformations. Here, we propose a novel approach to design a protein that adopts interconvertible alternative functional conformations, termed ″seesaw″ protein (SSP). An SSP was engineered by fusing GFP lacking the C-terminal β-strand and DHFR lacking the N-terminal β-s… Show more
