Protein

Protein supplements comes in various forms and are generally used to supplement the daily diet with the purpose increasing dietary protein intake. Among the multitude of protein products sitting on the shelves of your favorite health food store, you might have noticed hemp protein next to casein protein or whey protein. It is understandable if you overlook hemp protein if it is product that you are not familiar with or if the word hemp on the label evokes feelings of reservation. However, hemp…

The researchers of this article studied the GLI3 protein, which is a zinc fingered protein and encoded in humans. It is a copy of GLI family and is translocated in patients who possess the Greig cephalopolysyndactyly syndrome─GCPS. The mutation of the GLI3 protein is shown to cause various disorders such as, Pallister-Hall syndrome and postaxial polydactyl type A. The researchers were trying to demonstrate how a single gene mutation could cause these dissimilar developmental disorders in humans.…

contamination protein), where the amounts of exosome protein were still uncertain. To solve this issue, we tested 10% of each tag-labeled sample using LC-MS/MS before mixing, and obtained the amount of exosome protein by a label-free method. High-abundance contamination proteins including all forms of IgG and FN were deleted from the list of identified proteins. The remaining proteins were assumed to be derived from exosomes. Then, all peptide intensities of exosome proteins were log2…

Each lectin molecule usually comprises of two or more carbohydrate-combining sites, i.e., they are di- or polyvalent. Concanavalin A (a tetramer protein originally extracted from the jack-bean, Canavalia ensiformis) is a member of the legume lectin family and is a particular lectin that has been observed to be able to agglutinate a multitude of cell types, including myocytes, B-lymphocytes and fibroblasts, but for it to perform this action, it needs the presences of sugars which include mannose…

A protein has a precisely defined amino acid sequence which gives rise to its three dimensional structure which is essential to the protein’s function. These amino acids interact with one another to produce a specific folding pattern that produces the conformation of the protein. When one looks at the progression a protein makes in its folding complexity, it is clear that the folding is driven by the amino acid sequence alone. To understand this concept it is best to start with the primary…

compartment and controls several factors, such as protein and lipid composition of the membrane, fusion between distinct compartments, vesicle motility along microtubules, and interaction with the cytoskeleton. The membrane targeting process, as well as specific binding to GDI, requires post-translational isoprenylation (geranylgeranyl moieties) of the two Cys residues at or near the C-terminus of Rab (Chavrier et al., 1991; Ullrich et al., 1993). √ Rab proteins, as all GTPases, alternate…

Function of potyvirus proteins The Potyviruses genome contains one open reading frame (ORF) which is translated as a large polyprotein (between 340k and 368k), that is cleaved into 10 functional proteins (Riechmann et al., 1992) such as: Protein P1, HC-Pro, P3 protein, CI, NIa , NIb, 6K1, 6K2, VPg. The potyviral P1 protein is a serine protease that cleaves at its own C-terminus (Verchot et al., 1991). This is the most divergent potyviral protein in size (30-63 kDa) and sequence except protease…

transcription and translation of protein synthesis. What is DNA? DNA is a nucleic acid that carries the genetic information in cells and some viruses, consisting of two long chains of nucleotides twisted into a double helix and joined by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine. DNA sequences are replicated by the cell prior to cell division and may include genes, intergenic spacers, and regions that bind to regulatory proteins. DNA A. adenine…

1. PROTEIN Introduction: Protein are the central to life because they control almost all cellular processes, including initiating most of the reactions that occur in the living thing cells. They are one of the building blocks of body tissue and also can serve as fuel source. They are naturally occurs which means that they are made by living cells, like animals, bug, fungi and even human. They can interact with one another and other biological macro mules to form complex assemblies.…

Proteins Molecules Building materials for cells. Cells have organelles such as mitochondria, lysosomes, vesicles, etc. It is estimated that the body has over ten trillions cells Carry oxygen, build tissue, copy DNA for the next generation and do the work needed by the body. Deoxyribonucleic acid contains the blueprint for proteins and replication of itself mRNA transcribes DNA, tRNA translates mRNA into proteins. A pattern on nucleotide on a DNA strand is called a gene. The Central Dogma of…
