Papovaviridae, referred to in Fig. 2.1 have now been separated into Polyomaviridae and Papillomaviridae. d Enterovirus, referred to in Fig. 2.1 is a genus of the Picornaviridae. e Virions are often pleiomorphic. Download: Download full-size image FIGURE 2.1. Relative sizes and shapes of rep...
Here, we report the structure of a PSII–ACPII supercomplex from the cryptophyteChroomonas placoideaby cryo-electron microscopy (cryo-EM). The structure reveals that PSII–ACPII consists of a PSII dimer and twelve ACPII monomers forming four linear trimers, as well as a Chla-binding Psb-γ...
symmetry in the relaxed state of muscle5,6,7. The pairs of heads of three myosin molecules protrude from the backbone at regular intervals to form a ‘crown’ of heads, with successive crowns axially separated by about 143 Å. The interaction of the myosin motor domains with the thin f...
The lipopolysaccharide (LPS) is the major constituent of the outer leaflet of the outer membrane of Gram-negative bacteria. Its lipid A moiety is embedded in the membrane and serves as an anchor for the rest of the LPS molecule. The outermost repetitive
We were able to distinguish different topographic types of granulocytes on the basis of the pattern of segregation. Five topographic types were detected using dual-colour FISH in two-lobed nuclei. The segregation of four sets of genetic structures could be studied with the aid of repeated FISH ...
In the Arabian Sea, southeast of the Arabian peninsula, an oceanic dipole, named the Ras Al Hadd (RAH) dipole, is formed each year, lying near the Ras Al Hadd cape. The RAH dipole is the association of a cyclonic eddy (CE) to the northeast, with an anticyclonic eddy (AE) to the...
Structure Design and Mechanical Characteristics Analysis of Steel Bracing Structure of Porous Fences Taking the vertical-parallel and vertical-oblique types steel bracing structure,which are applied in the porous fences engineering equipments of a power pl......
Gene duplication, a major evolutionary path to genomic innovation, can occur at the scale of an entire genome. One such "whole-genome duplication" (WGD) event among the Ascomycota fungi gave rise to genes with distinct biological properties compared to small-scale duplications. Results We studied...
The crystal and electronic structures of the VN films were characterized by a combination of high-resolution X-ray diffraction, low-energy electron diffraction, resonant soft X-ray absorption spectroscopy, and ultraviolet photoelectron spectroscopy. The electrical transport measurements indicate that the ...
The known compound oleanolic acid (1) and a new cycloartane glycoside cyclounifolioside A (2), which has the structure 6,16-di-O-acetyl-24R-cycloartan-6,16,24,25-pentaol 3-O--D-glucopyranoside, were isolated from Astragalus unifoliolatus Bunge. The structures of the isolated compounds...
