Rutile phase titania nanoneedles were deposited on the surfaces of the anatase phase titania nanotubes templated by natural cellulose substance by a hydrothermal process,giving a hierarchical structur
驱动蛋白颈链向马达头部的对接是驱动蛋白力产生的过程,此对接过程是通过颈链和马达头部之间的各种非键相互作用实现的。之前的研究结果发现,颈链的ASN334与马达头部的GLY77形成一条骨架氢键,此骨架氢键周围存在三个疏水氨基酸,这三个疏水氨基酸之间具有疏水相互作用,此结构被称为ASN latch,具有很高的强度。我们发现ASN latch高强度来源于疏水相互作用和氢键相互作用的配合。以ASN334与G

Interplay of secondary and tertiary structural formations as significant folding events is crucial for the folding progresses of proteins.Here,we performed independent MD simulations on the wild-type
The activity,structure and related function of key enzymes-[FeFe]-hydrogenase is discussed in this paper,which capable of catalyzing the molecular hydrogen for dissociating H2,or generating the revers
The crystal structure of complexes of [Tb(3-Br-4-MBA)3phen]2(1),[Ho(3-Br-4-MBA)3(phen)H2O]2(2),[Er(3-Br-4-MBA)3(phen)H2O]2(3) have been solved by single-crystal X-ray diffiaction methods.The complex 1
Genetically encoded calcium biosensors are valuable tools in cell biology and neuroscience.A FRET-based calcium biosensor Cameleon has received a great deal of optimization since it was released in 19
Tetraphenylethylene (TPE),an archetypal luminogen with aggregation-induced emission (AIE),was grafted to a salt-responsive peptide to yield a yet luminescent hydrogelator.After testing different param
Chemical cross-linking provides an effective avenue to reduce the conformational entropy of polypeptide chains and hence has become a popular method to induce or force structural formation in peptides
More and more evidences have shown that many biological important processes are related to the conformation and assembly state of specific gone,involved proteins and enzymes.In this report,we summariz
