  • Lysyl Trna Synthetase Research Paper

    Ryan Schoen Mrs. Lily Gu Protein Project - function October 20, 2014 Lysyl-tRNA Synthetase Lysyl-tRNA Synthetase has a couple known names, one of them being aminocyl tRNA. The major role of this protein is translation during protein synthesis. For a protein to be classified and placed into an amino acid group, its amino acid sequence must be properly translated. Transfer RNA helps translate the protein which helps with genetics. Aminoacyl tRNA synthetases are the enzymes that are responsible for the specific aminoacylation of tRNA (Yifat, 2013). Let’s take a more in depth look at the function of this protein by breaking it down. Lysyl, otherwise known as lysyl oxidase, is synthesized as a preproprotein, meaning it contains a nonpolar signal…

  • Chop1

    As a result of eIF2α phosphorylation in stressed cells, the cells produce ATF4 proteins in an attempt to restore cellular homeostasis; alternatively, ATF4 protein promotes CHOP expression in prolonged stressed conditions. Consequent to increased eIF2α phosphorylation, accumulation of CHOP mRNA, encoding a proapoptotic transcription factor, induces an apoptotic pathway leading to cellular death for the purpose of protection of neighboring cells. CHOP mRNA is alternatively spliced at the second…

  • Fatty Acid Synthesis: The Catalysis Process Of Biosynthesis

    simple compounds change or convert into other compounds or they join together to form macromolecules. Example: In this process gluneogenesis is responsible for the production of glucose from non carbohydrate originator. Actually biosynthesis is an enzyme-catalyzed process in which substrates are converted into complex compounds. 1. Biosynthesis of fatty acids: Synthesis of fatty acids take place in the crystal. The enzymes of fatty acid synthesis are wrapped in a complex called fatty acid…

  • Dopamine Reaction Lab Report

    dopamine active transporter is a 12 integral membrane-spanning protein that moves the neurotransmitter dopamine out of the synapse back into cytosol terminating therefore the signal of the neurotransmitter. The dopamine reuptake via DAT is the primary mechanism from which dopamine is cleared from synapses. Its function requires the binding and cotransport of two Na+ ions and one Cl− ion with the dopamine substrate. The driving force for DAT-mediated dopamine reuptake is the ion concentration…

  • Mitochondria Research Paper

    pore-forming membrane proteins (porins), such as the voltage-dependent anion channel VDAC [19]. Any larger molecules, especially proteins, have to be imported by special translocases. Because of its porosity, there is no membrane potential across the outer membrane. By contrast, the inner membrane is a tight diffusion barrier to all ions and molecules. These…

  • Ferritin Research Paper

    How Ferritin was first isolated and how it is isolated now The protein ferritin is formed from two classes of subunits, H and L, in a ratio which vary in different cell types. The H-type are subunits associated with rapid uptake of iron and are predominantly from the red blood cells. Subunits that take up iron much slower are designated L-types. A third type subunit, M, is found in amphibians and is similar to the H subunit. The M-types are predominant in the liver. Once synthesized, ferritin…

  • Essay On S. Aureus

    S.aureus can be sensitized to B-lactams by preventing WTA biosynthesis through inactivation of TarO, which catalyses the first step of the WTA pathway(Maki,Campbell). This identified WTA biosynthesis as an attractive target for novel strategies to treat MRSA. WTAs are structurally diverse anionic polymers covalently attached to PG(Vollmer,Swoboda) and in S.aureus consist of a polyribitol-phosphate backbone of 11-40 repeating units(Xia10) decorated with three tailoring modifications:…

  • Yeast Expression

    higher eukaryotes. An increasing number of yeast strains are available for protein expression that are said to increase the yield of the protein, improves the affinity tagging of the proteins, reduces protein breakdown, allows the addition of non-native amino acids (Selenomethionine) into the protein and defines the composition of N-glycan in the protein produced. Following are the existing genera of yeast…

  • Fatty Acid Lab Report

    The chain lengths of the fatty acids in naturally occurring triglycerides vary, but most contain 16, 18, or 20 carbon atoms. Natural fatty acids found in plants and animals are typically composed of only even numbers of carbon atoms, reflecting the pathway for their biosynthesis from the two-carbon building-block acetyl CoA. Bacteria, however, possess the ability to synthesize odd- and branched-chain fatty acids. As a result, ruminant animal fat contains odd-number of fatty acids, such as 15,…
