Mechanisms and kinetics of beta-hairpin formation.
Thermodynamics and kinetics of off-lattice models with side chains for the beta-hairpin fragment of immunoglobulin-binding protein and its variants are reported. For all properties (except refolding time tau(F)) there are no qualitative differences between the full model and the Go version. The validity of the models is established by comparison of the calculated native structure with the Prote...
متن کاملMechanisms and kinetics of b-hairpin formation
Thermodynamics and kinetics of off-lattice models with side chains for the b-hairpin fragment of immunoglobulin-binding protein and its variants are reported. For all properties (except refolding time tF) there are no qualitative differences between the full model and the Go# version. The validity of the models is established by comparison of the calculated native structure with the Protein Dat...
متن کاملA statistical mechanical model for beta-hairpin kinetics.
Understanding the mechanism of protein secondary structure formation is an essential part of the protein-folding puzzle. Here, we describe a simple statistical mechanical model for the formation of a beta-hairpin, the minimal structural element of the antiparallel beta-pleated sheet. The model accurately describes the thermodynamic and kinetic behavior of a 16-residue, beta-hairpin-forming pept...
متن کاملStructural parameters affecting the kinetics of RNA hairpin formation
There is little experimental knowledge on the sequence dependent rate of hairpin formation in RNA. We have therefore designed RNA sequences that can fold into either of two mutually exclusive hairpins and have determined the ratio of folding of the two conformations, using structure probing. This folding ratio reflects their respective folding rates. Changing one of the two loop sequences from ...
متن کاملModeling the mechanism of CLN025 beta-hairpin formation.
Beta-hairpins are substructures found in proteins that can lend insight into more complex systems. Furthermore, the folding of beta-hairpins is a valuable test case for benchmarking experimental and theoretical methods. Here, we simulate the folding of CLN025, a miniprotein with a beta-hairpin structure, at its experimental melting temperature using a range of state-of-the-art protein force fie...
