Protein biosynthesis

the blood brain barrier via the L-type amino acid carrier. Excessive levels of Phe in the blood saturates these transporters and subsequently cause a decrease in transportation of other large neutral amino acids into the brain which is required for protein and neurotransmitter synthesis (Blau et al., 2010). Neurological…

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:…

Insulin, one of the most important peptide hormone in the body, which plays significant role in maintaining the blood glucose level in the body. Under certain physiological conditions such as pregnancy, the body mechanism changes due to elevated levels of certain secretory factor like leptin, plasminogen activator inhibitor-1, TNF-α, plasminogen activator and testosterone (McLachlan et al., 2006), which produces certain adverse effects, insulin resistance being the most prominent one, where the…

RgpB (ArgX protease and a key P. gingivalis virulence factor), F subunit of the enzyme alkyl hydroperoxide reductase (needed to provide bacterial adaptation to the oxygen stress) and ferritin, while the gene encoding for a polysaccharide biosynthesis-related protein was among the down-regulated genes [29]. The results suggest two likely mechanisms of catecholamine activity on P. gingivalis and possibly other anaerobic species: an increase in the expression of some virulence…

Phosphonates as inhibitors for Pks13-TE Hypothesis for the aim 1 of the proposed project is that the fluorinated α–Aminophosphonates as a covalent irreversible inhibitor for the Mtb Pks13-TE by scission of the P-C bond. Previous studies have shown the fluorinated aminophosphonates (FAPs) demonstrated serine esterases inhibition via scission of the P-C bond as shown in Figure 2.1.A 4. FAPs are known to irreversibly inhibit serine esterases such as acetylcholinesterase16 , neuropathy target…

elements are considered as cofactors, catalysts and structural components for many cellular enzymes and proteins in the CNS. They also play roles in the homeostatic, regulatory mechanisms maintaining their concentrations in the CNS (Richardson and Ponka, 1997). They take part in neuronal activities such as neurotransmission, synaptogenesis, neurogenesis, neurite outgrowth, neurotransmitter biosynthesis, oxidative phosphorylation and oxygen transport (Hung et al., 2010). Each of these elements…

Sonic hedgehog signalling function during nervous system development 13354626 Katie O’Byrne words including references Sonic hedgehog (Shh) is a glycoprotein that is secreted by and diffuses through the developing nervous system. It is a member of the hedgehog family of signaling molecules. The Sonic hedgehog signaling cascade is an integral trafficking system that influences the pattering and growth processes involved in the development of multicellular organisms. Shh is particularly important…

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, due to this action of…

Charbill Klayme 0993551 Dr. Hye-Jeong Yeo Functions of SREBPs Abstract SREBPs are 1,150 Amino Acid long proteins that are used to activate cholesterolgenesis. SREBP-1a are used to induce all the response genes. The SREBP-2 are used to allow expression of the LDL receptor. Ubiquination, usually by the kinase GSK3, can be the weapon to destructing SREBPs. SREBP-1a will build more cholesterol and fatty acids in rats and mice when it is over expressed. The SREBP-1c are best studied in the…

three-dimensional structure of a protein not only defines its shape and size, but also its function. Proteins consist of a long chain of 20 amino acids folded up into complex shapes. Each nonpolar amino acid folds into the interior of the proteins during the folding stage, as they are hydrophobic. The primary and secondary structure determines the hydrophobicity of a protein. Each nonpolar amino acid folds into the interior of the proteins during the folding stage. For instance, membrane…
