Streptomycineae
The ''Streptomycetaceae'' are a family of ''Actinomycetota'', making up the monotypic order ''Streptomycetales''. It includes the important genus ''Streptomyces''. This was the original source of many antibiotics, namely streptomycin, the first antibiotic against tuberculosis. Genomics Sequence alignments of actinomycetotal genomes have led to the identification of three conserved signature indels which are unique to the order Streptomycetales. The enzyme PBGD contains a four-amino-acid insertion which is present in all ''Streptomyces'' species and ''Kitasatospora setae'', but not any other Actinomycetota. Similarly, a one- amino-acid insertion is present in a conserved region of adenylate kinase and is found in all ''Streptomyces'' species and '' K. setae'', but is not found in any other Actinomycetota. Five conserved signature proteins have also been identified which are present in various sequenced ''Streptomyces'' species, but not in ''K. setae''; however, as the complete ...

Conserved Signature Indels
Conserved signature inserts and deletions (CSIs) in protein sequences provide an important category of molecular markers for understanding phylogenetic relationships. CSIs, brought about by rare genetic changes, provide useful phylogenetic markers that are generally of defined size and they are flanked on both sides by conserved regions to ensure their reliability. While indels can be arbitrary inserts or deletions, CSIs are defined as only those protein indels that are present within conserved regions of the protein. The CSIs that are restricted to a particular clade or group of species, generally provide good phylogenetic markers of common evolutionary descent. Due to the rarity and highly specific nature of such changes, it is less likely that they could arise independently by either convergent or parallel evolution (i.e. homoplasy) and therefore are likely to represent synapomorphy. Other confounding factors such as differences in evolutionary rates at different sites or amon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Outgroup (cladistics)
In cladistics or phylogenetics, an outgroup is a more distantly related group of organisms that serves as a reference group when determining the evolutionary relationships of the ingroup, the set of organisms under study, and is distinct from sociological outgroups. The outgroup is used as a point of comparison for the ingroup and specifically allows for the phylogeny to be rooted. Because the polarity (direction) of character change can be determined only on a rooted phylogeny, the choice of outgroup is essential for understanding the evolution of traits along a phylogeny. History Although the concept of outgroups has been in use from the earliest days of cladistics, the term "outgroup" is thought to have been coined in the early 1970s at the American Museum of Natural History. Prior to the advent of the term, various other terms were used by evolutionary biologists, including "exgroup", "related group", and "outside groups". Choice of outgroup The chosen outgroup is hypothes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genetic Markers
A genetic marker is a gene or DNA sequence with a known location on a chromosome that can be used to identify individuals or species. It can be described as a variation (which may arise due to mutation or alteration in the genomic loci) that can be observed. A genetic marker may be a short DNA sequence, such as a sequence surrounding a single base-pair change ( single nucleotide polymorphism, SNP), or a long one, like minisatellites. Background For many years, gene mapping was limited to identifying organisms by traditional phenotypes markers. This included genes that encoded easily observable characteristics such as blood types or seed shapes. The insufficient number of these types of characteristics in several organisms limited the mapping efforts that could be done. This prompted the development of gene markers which could identify genetic characteristics that are not readily observable in organisms (such as protein variation). Types Some commonly used types of genetic ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adenylate Kinase
Adenylate kinase ( ECbr>2.7.4.3 (also known as ADK or myokinase) is a phosphotransferase enzyme that catalyzes the interconversion of the various adenosine phosphates (ATP, ADP, and AMP). By constantly monitoring phosphate nucleotide levels inside the cell, ADK plays an important role in cellular energy homeostasis. Substrate and products The reaction catalyzed is: ATP + AMP ⇔ 2 ADP The equilibrium constant varies with condition, but it is close to 1. Thus, ΔGo for this reaction is close to zero. In muscle from a variety of species of vertebrates and invertebrates, the concentration of ATP is typically 7-10 times that of ADP, and usually greater than 100 times that of AMP. The rate of oxidative phosphorylation is controlled by the availability of ADP. Thus, the mitochondrion attempts to keep ATP levels high due to the combined action of adenylate kinase and the controls on oxidative phosphorylation. Isozymes To date there have been nine human ADK protein isoforms ide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
