Nicrophorus Pustulatus
''Nicrophorus pustulatus'', also known as the pustulated carrion beetle or blistered burying beetle, is a species of burying beetle that was described by Johann Karl Wilhelm Illiger in 1807. This species is native to North America. ''N. pustulatus'' exhibits unique habitat utilization and breeding behaviour relative to other members of the genus. This species may be the only described example of a true parasitoid targeting a vertebrate host. Taxonomy Phylogeny ''N. pustulatus'' is one of over 60 extant species in the genus ''Nicrophorus''. This genus belongs to the subfamily Nicrophorini, Nicrophorinae (sexton beetles), which is one of two subfamilies in the family Silphidae (carrion beetles, large carrion beetles, or burying beetles). The family Silphidae belongs to the superfamily Staphylinoidea, infraorder Staphyliniformia, suborder Polyphaga, and order Beetle, Coleoptera. The genus ''Nicrophorus'' is hypothesized to have evolved in the Cretaceous, Cretaceous Period approx ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burying Beetle
Burying beetles or sexton beetles, genus ''Nicrophorus'', are the best-known members of the family Silphidae (carrion beetles). Most of these beetles are black with red markings on the elytra (forewings). Burying beetles are true to their name—they bury the carcasses of small vertebrates such as birds and rodents as a food source for their larvae. They are unusual among insects in that both the male and female parents take care of the brood. They are carnivores. The genus name is sometimes spelled ''Necrophorus'' in older texts: this was an unjustified emendation by Carl Peter Thunberg (1789) of Fabricius's original name, and is not valid under the ICZN. The American burying beetle (''Nicrophorus americanus'') has been on the U.S. endangered species list since 1989. Reproduction Burying beetles have large club-like antennae equipped with chemoreceptors capable of detecting a dead animal from a long distance. After finding a carcass (most usually that of a small bird or a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nicrophorus Tomentosus
''Nicrophorus tomentosus'' (gold-necked carrion beetle or tomentose burying beetle) is a species of burying beetle that was described by Friedrich Weber in 1801. The beetle belongs to the family Silphidae which are carrion beetles. The beetles have sensitive antennae that contain olfactory organs. Thus, the beetle can locate dead animals (carcass), and then as the name suggests, can bury them. However, unlike other burying beetles, ''N. tomentosus'' does not completely bury these brood carcasses. They instead dig a shallow hole under the carcass and cover it with leaf litter. Recognition of these beetles can be distinguished by its black color with orange markings on the wing covers (elytra). Classification The genus name, '' Nicrophorus'', means “death carrier”; ' means "covered in short hair", referring to the pronotum. Description There are several characteristics that differentiate Silphidae from other families. One characteristic is that ''N. tomentosus'' is about 11.2 ...

CAD (gene)
CAD protein (carbamoyl-phosphate synthetase 2, aspartate transcarbamylase, and dihydroorotase) is a trifunctional multi-domain enzyme involved in the first three steps of pyrimidine biosynthesis. De-novo synthesis starts with cytosolic carbamoylphosphate synthetase II which uses glutamine, carbon dioxide and ATP. This enzyme is inhibited by uridine triphosphate (feedback inhibition). In 2015, the first observed pathological mutations of ''CAD'' were found in a four-year-old boy. CAD protein has been observed in the mid-piece of mammalian spermatozoa, among the mitochondria. Structure CAD protein has a molecular weight of 243 KDa. It is a polypeptide made up of four different domains which make for a multi enzyme unit: Glutaminase (GLN), carbamoyl phosphate synthetase (CPS II), Dihydroorotase (DHO) and aspartate transcarbamoylase (ATC). The protein assembles into ~1.5MDa hexamers. More specifically, the DHO domain assembles into dimers, and ATC domains do so into trimers. The ...

28S Ribosomal RNA
28S ribosomal RNA is the structural ribosomal RNA (rRNA) for the large subunit (LSU) of eukaryotic cytoplasmic ribosomes, and thus one of the basic components of all eukaryotic cells. It has a size of 25S in plants and 28S in mammals, hence the alias of 25S–28S rRNA. Combined with 5.8S rRNA to the 5' side, it is the eukaryotic nuclear homologue of the prokaryotic 23S and mitochondrial 16S ribosomal RNAs. Use in phylogeny The genes coding for 28S rRNA are referred to as 28S rDNA. The comparison of the sequences from these genes are sometimes used in molecular analysis to construct phylogenetic trees, for example in protists, fungi, insects, arachnids, tardigrades, and vertebrates. Structure The 28S rRNA is typically 4000–5000 nt long. Some eukaryotes cleave 28S rRNA into two parts before assembling both into the ribosome, a phenomenon termed the "hidden break". Databases Several databases provide alignments and annotations of LSU rRNA sequences for comparati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cytochrome C Oxidase Subunit 2
Cytochrome c oxidase subunit 2, also known as cytochrome c oxidase polypeptide II, is a protein that in humans is encoded by the MT-CO2 gene. Cytochrome c oxidase subunit II, abbreviated COXII, COX2, COII, or MT-CO2, is the second subunit of cytochrome c oxidase. It is also one of the three mitochondrial DNA (mtDNA) encoded subunits ( MT-CO1, MT-CO2, MT-CO3) of respiratory complex IV. Structure The ''MT-CO2'' gene is located on the p arm of mitochondrial DNA at position 12 and it spans 683 base pairs. The ''MT-CO2'' gene produces a 25.6 kDa protein composed of 227 amino acids. MT-CO2 is a subunit of the enzyme Cytochrome c oxidase () (Complex IV), an oligomeric enzymatic complex of the mitochondrial respiratory chain involved in the transfer of electrons from cytochrome c to oxygen. In eukaryotes this enzyme complex is located in the mitochondrial inner membrane; in aerobic prokaryotes it is found in the plasma membrane. The enzyme complex consists of 3-4 ...

Cytochrome C Oxidase Subunit I
Cytochrome c oxidase I (COX1) also known as mitochondrially encoded cytochrome c oxidase I (MT-CO1) is a protein that in humans is encoded by the ''MT-CO1'' gene. In other eukaryotes, the gene is called ''COX1'', ''CO1'', or ''COI''. Cytochrome c oxidase I is the main subunit of the cytochrome c oxidase complex. Mutations in MT-CO1 have been associated with Leber's hereditary optic neuropathy (LHON), acquired idiopathic sideroblastic anemia, Complex IV deficiency, colorectal cancer, sensorineural deafness, and recurrent myoglobinuria. Structure One of 37 mitochondrial genes, the ''MT-CO1'' gene is located from nucleotide pairs 5904 to 7444 on the guanine-rich heavy (H) section of mtDNA. The gene product is a 57 kDa protein composed of 513 amino acids. Function Cytochrome c oxidase subunit I (CO1 or MT-CO1) is one of three mitochondrial DNA (mtDNA) encoded subunits (MT-CO1, MT-CO2, MT-CO3) of respiratory complex IV. Complex IV is the third and final enzyme of the electron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
