This figure shows the different arrangement of the quaternary structure of the enzymes Rubisco as well as the molecular symmetry the enzyme has. In this model, the large subunits are blue and green, small subunits are yellow, and the substrate mimic is the red spheres. A) Rubisco from spinach is viewed to have L2S2 units in form 1 and also has a twofold axis of symmetry. B) The L8S8 hexadecamer is shown along the same twofold axis and C) along the 4-fold axis. D) The form II of Rubisco from Rhodospirillum rubrum shows the twofold symmetry. E) And F) The L10 Rubisco from Thermococcus kodakaraensis is shown along the twofold and fivefold axes. In the active site displayed as the red spheres, sulphate ions are bounded. (Andersson and Backlund, 2008).
Synthesis of Rubisco (Portis and Parry, 2009).

- According to the Greek mythology, Prometheus stole fire from Mount Olympus and created mankind from clay while Athena breathed life into clay figures. Not only the Greek mothology but also some other religions also carry “creation of human from clay” story, which was believed how life was created. Today, scientist know that the difference between then non-living objects and living objects is not a result of magic power. Life is made possible by the interaction of organic molecules, which consist of four major classes such as carbonhyrates, lipids, proteins and nucleic acids.... [tags: RNA, DNA, Protein, Ribosome]

- Sweetness. Lower molecular weight amino acids, except proline, are sweet irrespective of their configuration, and D-enantiomers of high molecular weight amino acids are generally sweet (Kemp & Birch, 1989). D-amino acids do not occur naturally but may be produced during food processing due to racemisation. There are currently no known natural peptides with a sweet taste (Weir, 1992). The synthetic peptide most recognised for its taste is L-aspartyl-L-phenylalanine methyl ester, i.e. aspartame, a low-caloric sweetener that is 180 times sweeter than sucrose....

- The primary goal of this research-inspired laboratory experience is to integrate genuine research into the biochemistry laboratory course for undergraduate students. This course introduces students to resources available to them via the Internet as well as standard experimental approaches and techniques used in modern biochemical research, through hands-on experimentation, discussion and application. Techniques will include bioinformatics tool, DNA purification and analysis, protein purification and quantification, enzymatic characterization, chromatography, electrophoresis, and spectroscopic analysis....

- ... The backbone of the nucleic acids consists of the interaction between phosphate groups and the hydroxide groups of nucleic acids. These are held together by covalent bonds called phosphodiester bonds. The helix itself is held together by hydrogen bonds. Although hydrogen bonds are weak individually, there are so many of them within DNA that the strands are held tightly together. Without basic chemistry the structure of DNA would be a mystery. The instructions to make a protein are coded by DNA.... [tags: function, protein, products]

- Hierarchical Structure of Proteins Molecular Cell Biology. 4th edition, Dec 18th, U.S. National Library of Medicine, This article intends to educate the reader on how exactly proteins function and their structure and how the various components of proteins work together to create one cohesive unit. This passage focuses on the spatial arrangement of proteins emphasizing its importance as key to understanding how exactly proteins work. In summary, this excerpt went over how proteins are a linear polymer of amino acids linked together by peptide bonds.... [tags: function, structure, cohesive, protein]

- ... It often occurs in bi-stable systems or in systems with a sensory threshold and when the input signal to the system is "sub-threshold". As pointed out for lower noise intensities, the signal does not cause the device to cross threshold, so little signal is passed through it. For large noise intensities, the output is dominated by the noise, also leading to a low signal-to-noise ratio. For moderate intensities, the noise allows the signal to reach threshold, but the noise intensity is not so large as to swamp it.... [tags: cellular function]

- Similar to other complexes observed, the components of the destruction complex function in cooperation. Binding interaction between APC and Axin helps to assemble the complex and facilitates phosphorylation (Fagotto & Henderson, 2002). Without the combined interactive force, β-catenin will not be effectively positioned since the phosphorylated site may not be oriented in the right direction. Free β-catenin is not normally recognized by GSK3 protein. Thus, only in the presence of APC and Axin is the kinase able to phosphorylate the amino acid (Orsulic & Peifer, 1996)....

- Protein F is an uncharacterized protein from the Coffea canephora organism, more commonly known as Robusta coffee. Its sequence consists of 420 amino acids, and is coded for by the gene GSCOC_T000168740011. This protein appears to be an aspartate aminotransferase, or an enzyme that catalyzes a reaction of α-ketoglutarate and aspartate to oxaloacetate and glutamate2. Based on a UniProt BLAST search, it appears that the protein is conserved in the organism Theobroma cacao, or cocoa. After analysis of the sequence through an NCBI BLAST search, it can be predicted that Protein F is most likely mitochondrial, especially when compared to similar proteins....

- Membranes play an integral function in trapping and securing metabolic products within the borders of a cell within an aqueous environment. Without a selectively permeable border surrounding sites of anabolic function, potential useful products of this metabolism would simply diffuse away in the aqueous environment contained within and surrounding the cell. However, securing metabolites within the cell also comes with a price of not being able to acquire potentially useful compounds from the surrounding environment....

- Cells The average person’s body contains 37.2 trillion cells (Jones, et al 446-457). Each cell fulfills a specific role within the body to help maintain the overall life and function of an individual. There is a conjoint configuration that can be found throughout most animal cells. Each part of a cell with its specific role is known as an organelle (Mader, Windelspecht 47). The plasma membrane, cytoplasm, nucleus, cytoskeleton, and other organelles are all essential parts of an animal cell (Mader, Windelspecht 47-58).... [tags: Cell, Protein, Organelle, Eukaryote]
