Cooperativity in biological systems
Living organisms can sense and respond to external and internal stimuli. Response isdemonstrated in many forms including modulation of gene expression profiles, motility,secretion, cell death, etc. Nevertheless, all forms share a basic property: they depend on sensingsmall changes in the concentration of an effector molecule or subtle conformational changes ina protein and invoking the appropri...
متن کاملCooperativity and biological complexity.
Cooperative binding effects pervade biology. Only a few basic principles are at play, but in different biological contexts cooperativity appears in distinct guises to achieve different ends. Here I discuss some of the manifestations of cooperativity that are most important in biology and drug discovery as they pertain to systems at different levels of complexity and also highlight aspects of th...
متن کاملAllostery and cooperativity revisited.
Although phenomenlogical models that account for cooperativity in allosteric systems date back to the early and mid-60's (e.g., the KNF and MWC models), there is resurgent interest in the topic due to the recent experimental and computational studies that attempted to reveal, at an atomistic level, how allostery actually works. In this review, using systems for which atomistic simulations have ...

متن کاملQuantum transients
Quantum transients are temporary features of matter waves before they reach a stationary regime. Transients may arise after the preparation of an unstable initial state or due to a sudden interaction or a change in the boundary conditions. Examples are diffraction in time, buildup processes, decay, trapping, forerunners or pulse formation, as well as other phenomena recently discovered, such as...
