Proteases in the MEROPS protease database have been subdivided into families and clans on the basis of evolutionary relationships (http://merops.sanger.ac.uk) (Rawlings et al., 2014). A protease clan refers to proteases derived from a single common ancestor, and clans are subdivided into families. A protease family refers to a sub-group of proteases that share sequence similarity, either throughout the entire protein sequence or only within the catalytic domain. The Arabidopsis thaliana genome encodes 879 known and putative proteases, corresponding to approximately 3.2% of all Arabidopsis protein-coding genes (The Arabidopsis Information Resource). These proteases are distributed over 60 families that belong to around 30 different clans
The importance of identification of a certain microorganisms can range between a life threatening diseases to a creation of certain antibiotic. Understanding the principals of living microbes and identifying my unknown bacteria through numerous biochemical and metabolism tests, with the outmost confidence, Proteus vulgaris had the precise qualifications. The point of this report is to further explore the identification of my unknown bacteria by revealing the results of the experiments and comparing them to the other six known bacteria: Micrococcus luteus, Staphylococcus aureus, Staphylococcus epidermidis, Alcaligenes faecalis, Escherichia coli, and Proteus vulgaris that were used in the lab, as well as comparing and
Since we have already known the amino sequence of the protein in previous step, we can narrow down the targeting ubiquitin ligase based on existing research data such as papers, NCBI data.
The newly formed ookinete survives in the harsh protease rich environment of the midgut due to protease resistant covering (Gass and Yeates, 1979). Carter and Kumar (1985) observed that ookinete surface proteins are responsible for protecting ookinetes from protease enzymes attack (Carter et al., 1988). These and other parasite surface proteins are also candidates for an antizygote-ookinete transmission-blocking
Researchers at George Washington University have been working on a vaccine to prevent infection from the hookworm parasite for years and sought out volunteers that would let these parasitic worms burrow into their skin. In order to effectively study the hookworm, the researchers needed to find healthy volunteers that would allow the hookworm parasites to infiltrate their bodies and live in there for several months and also diseased participants to compare the data that they would collect. However, people weren’t interested in doing the clinical trial when they found out they would have parasites sucking on their blood through their intestines. After searching for months, the GW team found a small group of volunteers to take on the task
Proteus Mirabilis is a motile bacterium that exists freely in water and soil; it may also be said to be a parasite that colonizes the human urinary tract. It exists in flagella or rod form as a gram-negative bacterium that displays uropathogenic virulence. Proteus Mirabilis is known to persist and live in people due to its unique virulence factors. Patients who have structural modifications within their urinary tract such as internal catheters are often deemed to be at high risk of contracting diseases such as pyelonephritis and cystitis, which are caused by Proteus Mirabilis (Jacobsen &Shirtliff, 2011). Individuals who have long-term catheters in their tracts face a high risk of suffering from urea hydrolysis and kidney/
Primase and helicase proteins are the essential components of the DNA replication machinery required for the synthesis of short RNA primers and the unwinding of the DNA, respectively. When these activities are encoded on the same polypeptide chain, as seen in many double-stranded DNA viruses, their proximity is hypothesized to confer several functional advantages. The aim of this study was to investigate the origin and evolutionary relationships of different combinations of primase-helicase bifunctional proteins that are prevalent in the virus world but also present sporadically in bacteria, archaea and eukaryotes. For this purpose, sequence analysis, phylogenetic relationships and coevolution of primase and helicase domains of the bifunctional
In most instances, protein molecules are usually embedded from hundreds to thousands of amino acids. A repertoire of twenty different amino acids, joined in any possible sequence allows the existence of an inconceivably large number of proteins that is infinite in nature.
One of the biggest advances has come from molecular analysis of common ancestry. Compiling molecular phylogenies that focus
It can be argued, however, Julia’s attention-grabbing rending and mangling of Proteus’ letter not only illuminates the commonplace role archetypal lovers and, in turn, dramatists must continuously play in Elizabethan society, but also questions mankind’s need to rebel versus an artificial state like the inability to act according to one’s own desires. While Julia’s dismissal of Elizabethan rites (social customs, practices and conventional acts) is merely temporary, her ability to disturb tradition drastically chafes against Shakespeare’s resolution to abide by literary conventions (the forced bond between Julia and Proteus), thus demanding critical analysis. Thinking with Dionysian ritual, this essay integrates bodily sensation and impulsive
This alarm anti-protease is secreted at the site of injury in response to primary cytokines like interleukin-1 (IL-1) and tumour necrosis factor (TNF), making them possibly the first line of defence in the anti-proteinase network (Sallenave, 2000). Elafin is produced mainly by epithelia in the skin, upper gastrointestinal tract, female reproductive tract, lungs and in low levels in serum. Its secretion is upregulated in the presence of inflammatory stimuli or conditions such as psoriasis and acute respiratory distress syndrome (Shaw, 2011), although some research have shown that uncontrolled protease activity may lead to its proteolytic cleavage (Small, 2015). This was confirmed in a study by Guyot et al which demonstrated that the involvement of purified NE in
Just as members in the same family often resemble each other, similarly structured molecules are often grouped in the same category. There are several methods of comparing amino acid sequencing and determining how closely they are related. A simple example is the sequence-comparison method. Sequence databases are searched for a specific amino acid sequence of unknown characteristics. A set of molecules that are similar in structure can give insight into the properties of the unknown sequence of amino acids.
Apolipoprotein(A) is a homologue of plasminogen and contains several copies of KRINGLE 4 plasminogen, a single copy of KRINGLE 5 plasminogen and an inactive protease domain (2).
EST sequences with vector sequence were edited using Phrap “cross-match” application. Contig Assembly Program 3 (Cap3) was used to assemble the sequences obtained from sequencing for analysis while Consed/Autofinish software was used to control the sequence assembly. All sequences were assembled separately into contigs. BLAST of sequences was conducted to determine the gene homology in order to connect their functions. Unique sequences were analysed for biological characteristics as well as functional annotation using program BLAST2GO. New genes can then be identified eventually.
D.Thompson, Desmond G.Higginsand and Toby J.Gibson [1] innovated pairwise alignment of very closely related sequence can be carried out very accurately, and this guarantees a mathematically optimal alignment. It is very useful starting point for as it helps define the major blocks of similarity manual refinement. W J Wilbur and David J Lipman [2] developed a global algorithm for comparing two Amino acid sequences, and also the algorithm involves the construction of an optimal alignment. It is an algorithm for fast alignment and comparison of two nuclide acid and amino acid sequence, the number of protein molecules and nucleic acid fragments for which the sequences have been determined has grown into the thousands, it has become clear that
