Journal ArticleDOI
Ion permeation in K + channels occurs by direct Coulomb knock-on
TL;DR: In this article, Coulomb repulsion between adjacent ions is found to be the key to high-efficiency K(+) conduction, and the model offers an intuitive explanation for the high throughput rates of k(+) channels.
Journal ArticleDOI
Intrinsic ion selectivity of narrow hydrophobic pores.
Chen Song,Ben Corry +1 more
TL;DR: This work suggests that the intrinsic ion selectivity of biological pores of differing radii might also play a role in determining their selectivity, in addition to the more common explanations based on electrostatic effects.
Journal ArticleDOI
Phospho-selective mechanisms of arrestin conformations and functions revealed by unnatural amino acid incorporation and 19 F-NMR
Fan Yang,Fan Yang,Xiao Yu,Chuan Liu,Changxiu Qu,Zheng Gong,Hongda Liu,Fahui Li,Hong-Mei Wang,Dongfang He,Fan Yi,Chen Song,Changlin Tian,Kunhong Xiao,Kunhong Xiao,Jiangyun Wang,Jin-Peng Sun +16 more
TL;DR: The identified receptor-phospho-selective mechanism for arrestin conformation and the spacing of the multiple phosphate-binding sites in the arrestin enable arrestin to recognize plethora phosphorylation states of numerous GPCRs, contributing to the functional diversity of receptors.
Journal ArticleDOI
Crystal Structure and Functional Mechanism of a Human Antimicrobial Membrane Channel.
Chen Song,Conrad Weichbrodt,Evgeniy S. Salnikov,Marek Dynowski,Björn O. Forsberg,Burkhard Bechinger,Claudia Steinem,Bert L. de Groot,Ulrich Zachariae,Kornelius Zeth,Kornelius Zeth +10 more
TL;DR: In this paper, the authors presented the X-ray crystal structure as well as solid-state NMR spectroscopy, electrophysiology, and MD simulations of human dermcidin in membranes that reveal the antibiotic mechanism of this major human antimicrobial, found to suppress Staphylococcus aureus growth on the epidermal surface.
Journal ArticleDOI
Tunable Magnetism in Carbon-Ion-Implanted Highly Oriented Pyrolytic Graphite†
Huihao Xia,Weifeng Li,You Song,Xinmei Yang,Xiangdong Liu,Mingwen Zhao,Yueyuan Xia,Chen Song,Tianwei Wang,Dezhang Zhu,Jinlong Gong,Zhiyuan Zhu +11 more
TL;DR: In this paper, a collaborative group of US and German scientists provided the first direct experimental evidence of p-electron ferromagnetism in metal-free carbon films by using X-ray magnetic circular dichroism (XMCD).
