Chick embryo ribosome crystals: analysis of bonding and functional activity in vitro.
The intracellular ribosome crystals from chick embryos incubated at 5 degrees C have been isolated; stable products of their dissociation were shown to include single ribosomes, tetramers of ribosomes, and tetramers of large subunits. Conditions were found for the formation in vitro not only of the p4 crystals from ribosomal tetramers but also of the tetramers themselves from free ribosomes. Th...
متن کاملRibosome crystals in necrotizing cells from the posterior necrotic zone of the developing chick limb.
Ribosome and ' protein crystals' were observed in electron micrographs of degenerating cells from the posterior necrotic zone (PNZ) of developing chick limbs, stages 22 through 24. Ribosome crystals were made up of basic units of 4 ribosomes arranged in a square tetramer. They were monomorphic with the surface lattice being of the p4 plane group. The i-ribosomethick sheets of crystals were ofte...
متن کاملRhombellanic Crystals and Quasicrystals
Design of some crystal and quasicrystal networks, based on rhombellane tiling,is presented. [1,1,1]Propellane,is a synthesized organic molecule; its hydrogenated form, the bicyclo[1.1.1]pentane,may be represented by the complete bipartite graph K2,3 which is the smallest rhombellane. Topology of translational and radial structures involving rhombellanes is described in terms of vertex symbol, c...
متن کاملRibosome cycling
Eating Staph he scavenger receptor CD36 is required for binding and internalization of Staphylococcus aureus , report Stuart et al. (page 477). After recognizing lipoteichoic acid on the bacterial surface, CD36 teams up with toll-like receptors, TLR2/6, to trigger expression of pro-inflammatory cytokines. Researchers already knew that CD36 recognized apoptotic cells in both mammals and flies. I...
متن کاملRibosome structure
A ribosome is a vast assembly consisting of proteins and RNAs. The molecular mass adds up to approximately 2.5 MDa, and it is the largest asymmetric entity whose structure has been solved in human history. The first step of X-ray structure analysis is to acquire wellordered crystals of the target material. Generally speaking, crystallization becomes more difficult as the size of the molecule in...
