RNA Editing
A process that changes the nucleotide sequence of mRNA from that of the DNA template encoding it. Some major classes of RNA editing are as follows: 1, the conversion of cytosine to uracil in mRNA; 2, the addition of variable number of guanines at pre-determined sites; and 3, the addition and deletion of uracils, templated by guide-RNAs (RNA, GUIDE).
Tubulin
A microtubule subunit protein found in large quantities in mammalian brain. It has also been isolated from SPERM FLAGELLUM; CILIA; and other sources. Structurally, the protein is a dimer with a molecular weight of approximately 120,000 and a sedimentation coefficient of 5.8S. It binds to COLCHICINE; VINCRISTINE; and VINBLASTINE.
Comparison of base specificity and other enzymatic properties of two protozoan ribonucleases from Physarum polycephalum and Dictyostelium discoideum. (1/337)
Base specificity and other enzymatic properties of two protozoan RNases, RNase Phyb from a true slime mold (Physarum polycephalum) and RNase DdI from a cellular slime mold (Dictyostelium discoideum), were compared. These two RNases have high amino acid sequence similarity (83 amino acid residues, 46%). The base specificities of two base recognition sites, The B1 site (base recognition site for the base at 5'-side of scissile phosphodiester bond) and the B2 site (base recognition site for the base at 3'-side of the scissile bond) of the both enzymes were estimated by the rates of hydrolysis of 16 dinucleoside phosphates. The base specificities estimated of B1 and B2 sites of RNase Phyb and RNase DdI were A, G, U > C and A > or = G > C > U, and A > or = G, U > C and G > U > A, C, respectively. The base specificities estimated from the depolymerization of homopolynucleotides and those from the releases of four mononucleotides upon digestion of RNA coincided well with those of the B2 sites of both enzymes. Thus, in these enzymes, the contribution of the B2 site to base specificity seems to be larger than that of the B1 site. pH-stability, optimum temperature, and temperature stability, of both enzymes are discussed considering that RNase Phyb has one disulfide bridge deleted, compared to the RNase DdI with four disulfide bridges. (+info)The uptake and metabolism of uridine by the slime mould Physarum polycephalum. (2/337)
1. Uridine is taken up by microplasmodia of Physarum polycephalum via a saturatable transport system with an apparent Km of 29 muM. An intracellular concentration significantly higher than that in the growth medium is attained, suggesting that the uptake is an active process. Both deoxyribonucleosides and ribonucleosides are competitive inhibitors of the uptake of uridine. 2. In contrast, the rate of entry of uridine into surface plasmodia is a linear function of the concentration of the nucleoside in the growth medium, and the uptake is not inhibited by other nucleosides. 3. As well as serving as a source of pyrimidine nucleotides for the synthesis of nucleic acids, uridine is also catabolised by P. polycephalum. Uracil accumulates in the growth medium and there is also significant conversion of C-2 of the pyrimidine ring to CO2. The proportion of uridine subject to catabolism in surface plasmodia is less than that observed for microplasmodia. (+info)Sterol content of the Myxomycetes Physarum polycephalum and P. flavicomum. (3/337)
The sterol content of two Myxomycetes, Physarum polycephalum and P. flavicomum has been examined. The sterols of the two species are apparently identical, the two major sterols in each being poriferasterol and 22-dihydroporiferasterol. Threee minor sterols are probably delta5-ergostenol, ergostanol, and poriferastanol. The triterpenoids of the two species differ in that, though lanosterol was identified in both, 22-dihydrolanosterol was indicated only in P. flavicomum. The occurrence of lanosterol together with a typical mixture of plant sterols is somewhat unusual. (+info)The subunit structure of chromatin from Physarum polycephalum. (4/337)
Nucleosome DNA repeat lengths in Physarum chromatin, determined by nuclease digestion experiments, are shorter than those observed in most mammalian chromatin and longer than those reported for chromatin of certain other lower eukaryotes. After digestion with staphylococcal nuclease for short periods of time an average repeat length of 190 base pairs is measured. After more extensive digestion an average repeat length of 172 base pairs is measured. Upon prolonged digestion DNA is degraded to an average monomer subunit length of 160 base pairs, with only a small amount of DNA found in lengths of 130 base pairs or smaller. Mathematical analysis of the data suggests that the Physarum nucleosome DNA repeat comprises a protected DNA segment of about 159 base pairs with a nuclease-accessible interconnecting segment which ranges from 13 to 31 base pairs. The spacing data are compatible with measurements from electron micrographs of Physarum chromatin. (+info)A cytoplasmic inhibitor of DNA polymerase from the plasmodia of Physarum polycephalum. (5/337)
A factor which inhibited DNA polymerase [EC 2.7.7.7] activity was isolated from the cytoplasm of plasmodia of true slime mold, Physarum polycephalum. This factor was purified by DEAE-Sephadex and CM-cellulose column chromatographies, heat treatment and gel filtration. This inhibitor was heat-stable, insensitive to trypsin [EC 3.4.21.4] and was not digested by RNase [EC 3.1.4.22] or DNase [EC 3.1.4.5]. The molecular weight was 16,000 as determined by gel filtration, and the isoelectric point was determined to be pH 10.1. In the presence of the inhibitor, Km for DNA in the DNA polymerizing reaction was markedly increased. The inhibitory effect was eliminated by addition of excess DNA, but the addition of excess enzyme or deoxyribonucleoside triphosphates had no effect on the inhibition. (+info)Photoreceptor pigment that induces differentiation in the slime mold Physarum polycephalum. (6/337)
An extract of small molecules (molecular weight less than 500) of the slime mold Physarum polycephalum undergoes a shift in ultraviolet-visible absorption spectrum upon illumination. This illumination also confers on the extract the ability to induce sporulation when injected into a starved, unilluminated slime mold. The spectral shift and appearance of the sporulation-inducing activity both occur regardless of whether the illumination is carried out on an intact slime mold or on the plasmodium-free extract itself. Thin-layer chromatography resolves the slime mold extract into four major visible fractions. One of these has high sporulation-inducing activity after illumination in vitro. (+info)Growth of Physarum gyrosum on agar plates and in liquid culture. (7/337)
The physical and nutritional requirements of the antibiotic-producing slime mold Physarum gyrosum were examined to develop a liquid medium for this myxomycete. Liquid culture is desired to expedite a useful scale of production of antibiotic materials for ease of isolation and structure study. Culture conditions were selected to favor antibiotic production rather than maximum growth. The medium devised consisted of 0.010 M potassium phosphate buffer (pH 6.0), 2% bakers' yeast, and 0.2% glucose and was supplemented with either 10(-7) M hemoglobin (preferred) or 2.0 ml of live Escherichia coli per 100 ml of culture medium grown to a steady-state population in nutrient broth. The slime mold, which contained some E. coli carried along with the inoculum, was allowed to grow as a surface plasmodium at 20 degrees C in the dark with weekly subculturing for stocks or for 10 days for antibiotic production. P. gyrosum produced the same antibiotic materials when grown in liquid medium as it did when grown on agar plates. A seeded plate disk assay against Bacillus cereus was employed to follow antibiotic activity. (+info)Ribosomal RNA genes in the amoebal and plasmodial forms of the slime mould Physarum polycephalum. (8/337)
1. The degree of homology between ribosomal RNA isolated from microplasmodia and amoebae of the slime mould Physarum polycephalum has been determined by competive hybridisation of the RNA from the two sources to homologous DNA in solution. The extent of competition was measured both by hybridisation to saturation and by following the kinetics of hybrid formation. In each case competition was found to be 100%, indicating that the ribosomal RNAs from the two, quite different vegetative forms of the organism exhibit a high degree of homology and are probably transcribed from the same genes. 2. The relationship between the amount of nuclear DNA that codes for ribosomal RNA (rDNA) and ploidy has been investigated in three strains of P. polycephalum which exhibit a 1:2:5 variation in the amount of DNA per nucleus. Ribosomal RNA saturation values were determined by hybridisation to DNA isolated from prophase nuclei of plasmodia. The proportion of rDNA was found to be constant at 0.16--0.18% of the total genome in the three strains. (+info)Physarum is a genus of unicellular slime molds in the class Myxomycetes, characterized by their vegetative state as a plasmodium, a multinucleate, syncytial mass that can migrate and forage for food.
"Physarum" is not a term that has a specific medical definition. It is a genus of slime molds, which are single-celled organisms that can behave as multicellular entities under certain conditions. They are often studied in biological research for their unique behaviors and abilities, but they do not have direct relevance to human medicine.
Physarum polycephalum is a species of plasmodial slime mold, a large single celled organism with multiple nuclei, that lives on decaying vegetation and demonstrates complex behaviors such as problem solving and maze navigation.
"Physarum polycephalum" is not a medical term, but a scientific name for a type of slime mold. It's a unicellular organism that behaves as a single entity, despite not having a true nervous system or muscles. It's often studied in biological research due to its unique abilities in problem-solving and adaptation.
However, if you're asking about the medical relevance of slime molds, they have been researched for their potential biomedical applications, such as drug discovery and toxicology studies. Some compounds produced by slime molds have shown promising antibiotic, antifungal, and anticancer properties. But it's important to note that these are early-stage research findings and further investigation is needed before any medical applications can be confirmed.
Cytoplasmic streaming, also known as cyclosis, is the active movement of organelles and other cytoplasmic components within the cell driven by cytoskeletal elements, typically observed in large plant cells and certain types of animal cells.
Cytoplasmic streaming, also known as cyclosis, is the movement or flow of cytoplasm and organelles within a eukaryotic cell. It is a type of intracellular transport that occurs in many types of cells, but it is particularly prominent in large, single-celled organisms such as algae and fungi.
During cytoplasmic streaming, the cytoplasm moves in a coordinated and organized manner, often in circular or spiral patterns. This movement is driven by the action of motor proteins, such as myosin, which interact with filamentous structures called actin filaments. The movement of the motor proteins along the actin filaments generates force, causing the cytoplasm and organelles to move.
Cytoplasmic streaming serves several functions in cells. It helps to distribute nutrients and metabolic products throughout the cell, and it also plays a role in the movement of organelles and other cellular components to specific locations within the cell. Additionally, cytoplasmic streaming can help to maintain the structural integrity of large, single-celled organisms by ensuring that their cytoplasm is evenly distributed.
'RNA editing' is a post-transcriptional modification process that involves the alteration of an RNA sequence, through insertions, deletions, or substitutions of nucleotides, from its template DNA, thereby increasing transcriptome and proteome diversity.
RNA editing is a process that alters the sequence of a transcribed RNA molecule after it has been synthesized from DNA, but before it is translated into protein. This can result in changes to the amino acid sequence of the resulting protein or to the regulation of gene expression. The most common type of RNA editing in mammals is the hydrolytic deamination of adenosine (A) to inosine (I), catalyzed by a family of enzymes called adenosine deaminases acting on RNA (ADARs). Inosine is recognized as guanosine (G) by the translation machinery, leading to A-to-G changes in the RNA sequence. Other types of RNA editing include cytidine (C) to uridine (U) deamination and insertion/deletion of nucleotides. RNA editing is a crucial mechanism for generating diversity in gene expression and has been implicated in various biological processes, including development, differentiation, and disease.
Tubulin refers to the family of globular proteins that form microtubules, key components of the cytoskeleton involved in maintaining cell structure, intracellular transport and mitosis.
Tubulin is a type of protein that forms microtubules, which are hollow cylindrical structures involved in the cell's cytoskeleton. These structures play important roles in various cellular processes, including maintaining cell shape, cell division, and intracellular transport. There are two main types of tubulin proteins: alpha-tubulin and beta-tubulin. They polymerize to form heterodimers, which then assemble into microtubules. The assembly and disassembly of microtubules are dynamic processes that are regulated by various factors, including GTP hydrolysis, motor proteins, and microtubule-associated proteins (MAPs). Tubulin is an essential component of the eukaryotic cell and has been a target for anti-cancer drugs such as taxanes and vinca alkaloids.
RNA in Protozoa refers to the ribonucleic acid molecules present in protozoans, which play crucial roles in various cellular processes such as protein synthesis, gene regulation, and as genetic material in certain viruses that infect protozoans.
I'd be happy to help! However, I believe there might be a slight confusion in your question. RNA stands for Ribonucleic Acid, which is a type of nucleic acid involved in various biological roles in the coding, decoding, regulation, and expression of genes. On the other hand, protozoan refers to a unicellular organism from the kingdom Protista, which includes a wide variety of simple eukaryotic organisms such as amoebas, paramecia, and plasmodium (the malaria-causing parasite).
There isn't a specific medical definition for "RNA, protozoan" since RNA is a molecule present in all living cells, including human cells, and protozoans are a group of organisms. However, I can tell you that RNA plays crucial roles in protozoan biology, such as acting as a messenger between DNA and ribosomes during protein synthesis or regulating gene expression.
If you have any further questions or need more specific information about RNA in protozoans, please let me know!

Its a bit off topic from plastic reduction but still important in the grand scheme of things.. Great Pacific Garbage Patch. You have probably heard about the Great Pacific Garbage Patch. Its large and full of plastic but not the recognizable plastic you can ban from fast food restaurants (although it is a good reminder to eat sustainable seafood). Its also one of five large patches of garbage in the oceans (not to mention all the other trash found throughout all water systems), it just seems to be the one that gets the most attention.. This article is from last year but it did the rounds on social again recently and people have been using it as a reason to stop straw bans. Straws seem to be a poster child for reducing single plastic use and have got a LOT of critics. Straw bans are not perfect. I know that, most people know that. If you need to use one, go ...
