Ribosomal protein mutants and their effects on plant growth and development
… containing an RNA catalytic core, drive protein synthesis in all living organisms. 80S cytoplasmic eukaryotic ribosomes are comprised of four rRNAs and approximately 80 ribosomal proteins (r-proteins). R-proteins are encoded by gene families with large families (average of twelve members) …

Molecular recognition in plant immunity
… disease-resistance genes, which generally encode proteins with nucleotide-binding and leucine-rich repeat domains (NB-LRRs). NB-LRRs are a large of proteins found in both plants and animals, with plant NB-LRRs further classified by the presence of N-terminal coiled-coil or toll-interleukin …

Simulation and Visualization of Dynamics in RNA·protein Complexes in Translation
… rRNA signatures and signatures in the ribosomal proteins (r-proteins) show that the rRNA signatures coevolved with both domain specific r-proteins and inserts in universal r-proteins. The largest bacterial structural rRNA signature with such a coevolutionary protein partner is found in the …

Serotonin 5-HT<sub/>2C</sub> receptors: Role in (+)-MDMA sensitization and distribution in the ventral tegmental area
… was not linked to reduced 5-HT<sub/>2C</sub>R protein expression in the ventral tegmental area (VTA), nucleus accumbens (NAc), or prefrontal cortex in either (+)-MDMA- or MK 212-pretreated rats. However, an up-regulation of 5-HT<sub/>2C</sub>R protein expression was observed in the VTA at 2 wks …

An E. coli small RNA inhibits translation initiation from a distance
… the initiating ribosomes while the chaperone protein Hfq plays a supporting role. Contrary to this widely accepted model, there are a few examples in the literature where the sRNA base pairs far from the SD region, yet translation of the target mRNA is still inhibited. Mechanistically, …

Evolution and assembly of the ribosome
… a large macromolecular assembly responsible for protein synthesis in all living cells. A typical bacterial ribosome consists of three ribosomal RNA (rRNA) molecules and approximately fifty ribosomal proteins (r-proteins), which are arranged into two subunits of unequal size and distinct function. …

Engineering durable late blight resistance to protect solanaceous plants
… which is recognised by the potato R3a protein, a member of the CC-NB-LRR type resistance gene family. However, the closely related virulent form, AVR3a<sup>EM</sup>, which is homozygous in more than 70% of wild <i>P. infestans</i> isolates, evades this recognition.Domain swapping …

Mechanisms and Evolution of Mitoribosomal Small Subunit Biogenesis
… the macromolecular machine responsible for all protein synthesis in the cell and is one of the ancient molecular machines involved in the transfer of genetic information to functional molecules. The ribosome is made up of two conserved ribonucleoprotein complexes: the large subunit, responsible …

Identification and molecular characterisation of elicitor-priming for resistance in tomato against <i>Botrytis cinerea</i>
… activity; 2) a cell-wall reinforcement through R protein activation, cellulose synthesis and PGs, PMEs and xyloglucan repression; 3) a fine-tuned potentiation of JA/JA-Ile synthesis and JA/ET/SA/ABA transcriptional regulation; 4) an induction of the lipid/fatty acid metabolism and phenylpropanoid …

Simulation and visualization of dynamics in RNA-protein complexes in translation
… information and synthesizing the corresponding proteins, is universal and found throughout the three domains of life. The flow of information in translation involves a series of distinct but highly conserved RNA·protein complexes with the ribosome being the largest ribonucleoprotein complex in …

Some properties and function of ribosomal proteins from the seeds of Pinus lambertiana
Functional roles of ribosomal proteins (r-proteins) on the structural properties of ribosomes from Pinus lambertiana were studied. For this purpose, r-proteins in the ribosome were dansylated with dansyl chloride (l-dimethylaminonaphthalene-5-sulfonyl chloride) dispersed on celite (DNS-Cl-celite); …

Genetic characterization of a dominant susceptible Rpp1 allele and analysis of quantitative resistance to Asian soybean rust
… the hypothesis that an overly abundant DS-R protein could interact with and presumably disrupt the functional Rpp1 protein, probably leading to dominant susceptibility. In addition to exploring the DS mechanism, new information about the Rpp1 gene that provides resistance to ASR, was also …

Exploiting crosstalk between growth and immunity in plants : the role of the <i>Phytophthora infestans</i> effector AVR2 in potato late blight
… is exemplified by pathogen effectors; secreted proteins which enter the plant cell and interact with host targets to facilitate infection. AVR2 is one such effector, secreted by the oomycete pathogen Phytophthora infestans; the pathogen responsible for potato late blight. AVR2 interacts with a …

Characterization of the metallo-ß-lactamase from Pseudomonas aeruginosa, IMP-1.
The rate at which pathogenic bacteria are gaining antibiotic resistance has become increasingly alarming. Major contributors of this antibiotic resistance in microbes are a class of enzymes known as β-lactamases. These enzymes are effective in breaking down the most commonly prescribed antibiotics …
