Dynamics of Myoglobin-CO with the Proximal Histidine Removed:Vibrational Echo Experiments
Myoglobin-CO Proximal Histidine Removed Vibrational Echo Experiments
2016/5/23
Picosecond infrared vibrational echo measurements from 60 to 300 K on CO bound to the active site of a mutant myoglobin, H93G(N-MeIm), are presented and compared to measurements on native myoglobin an...
Many Experiments for the Price of One:A Breakthrough in the Study of Gene Regulation
Price of One Gene Regulation
2015/6/18
Inside every cell that makes up a diminutive fruit fly is a vast, dynamic network of information—the genome whose ~15,000 genes allow that cell to function. In a study recently published as a Br...
Experiments prove 'stemness' of individual immune memory cells
Experiments prove stemness individual immune memory cells
2014/8/14
Researchers in Germany and the U.S. have proven for the first time that specific individual cells of the immune system, termed central memory T cells, have all the essential characteristics of adult t...
Effects of mammalian herbivore declines on plant communities: observations and experiments in an African savanna
abiotic gradients, community structure, East Africa
2015/11/13
In this study, we examined the interactive roles of soil,
rainfall and livestock in modulating the response of local
plant communities to large wildlife declines. We investigated
these interactions...
Theory of single-molecule experiments in the overstretching force regime
Theory of single-molecule experiments the overstretching force regime Biological Physics
2012/6/5
We present a statistical mechanics analysis of the finite-size elasticity of biopolymers, consisting of domains which can exhibit transitions between more than one stable state at large applied force....
