Each Ni atom is pseudo- tetrahedrally coordinated by an Ni-C a bond and an Ni(C=C) zc bond of a C~6 fragment formed by dimerization of two cod ligands and two bonds of the asymmetric CsMe 5 ring. The CsMe:ring bond dis- tances range from 1.407 to 1.461 A. Experimental. ...
Application of an intramolecular tropone-alkene photocyclization to the total synthesis of (.+-.)-dactylol The X-ray analysis supports the view that the metal soap has a double layer structure with molecular axes slightly inclined towards the basal plane. The... KS Feldman,MJ Wu,DP Rotella ...
AlphaFold can predict the structure of single- and multiple-chain proteins with very high accuracy. However, the accuracy decreases with the number of chains, and the available GPU memory limits the size of protein complexes which can be predicted. Here
Relationship between Structure and Dielectric Property in (1-x)(Na1/2Bi1/2)TiO3-xPbZrO3 Ceramics revealed that PZ addition prevented the arrangement of A-site cations, which caused random fields and non-uniform polarization in NBT–PZ solid solution.doi... JK Lee,JY Yi,KS Hong - 《Japane...
There are two types of Ni atoms, both octahedrally coordinated and linked together by oxygen sharing to form a three-dimensional network. Each oxygen atom is surrounded by three nickel atoms and one boron atom arranged in an irregular tetrahedron. 展开 ...
structure of an RNA and its ability to interact with proteins. Analysing in silico, in vitro and in vivo experiments, we find that the amount of double-stranded regions in an RNA correlates with the number of protein contacts. This relationship —which we call structure-driven protein ...
Each bilin’s 10th C atom (the central carbon between the rings B and C of the bilin) is shown as a dot. Dots are colored according to their protein subunits, as shown in Fig. 2h, and bilin distances were calculated based on the positions of dots. a Four identified pathways originated...
Here, we report an electron cryo-microscopy (cryo-EM) structure of a translocating SecA-SecY complex in a lipid environment. The translocating polypeptide chain can be traced through both SecA and SecY. In the captured transition state of ATP hydrolysis, SecA’s two-helix finger is close to...
