YP_001478954) was obtained from NCBI database (www.ncbi.nlm.nih.gov). A BLAST search of the amino acid sequence against Protein Data Bank (PDB) was performed to identify the three-dimensional structures that could share high sequence homology. The three-dimensional coordinates of the basic structure were obtained from the PDB. We built the three-dimensional structure of the SpChiD protein using the MODELLER (23) implemented in Discovery Studio 2.5 (Accelrys Inc.). The structural validation of…

some of three base sequence is a codon and each codon is related to an amino acid. These codons come together in a linear sequence and create a gene. Gene can be called as cipher that encrypts proteins. According to results of human genom project, there are approximately 20,500 genes and 500,000 proteins in human body.... In the Modern days of the civilization, biotechnology industry is working to both explore and exploit Deoxyribonucleic…

Chromatography, LDH was separated by hydrophobicity using Cibacron Blue Agarose as a ligand. Once the samples were loaded into the column, wash buffers were used to elute down proteins that didn’t bind to the ligand. Afterwards, 1M NaCl was used to disrupt the interaction between the ligand and the target protein so that LDH proteins could elute down. Through this elution process, 20 fractions were collected after 1M NaCl was added and LDH spot test was performed. Graph 1: Plot of elution…

corpuscles. This interaction is responsible for the initial pain and swelling that is associated with a bee sting. (Collison, 41) However, the properties that make melittin toxic can also be harnessed for therapeutic purposes. Melittin is a small protein containing 26 amino acids that comprises 50% of bee venom’s dry weight. (Collison, 40) It exists primarily in two distinct forms. In water it exists as a soluble folded tetramer, but can spontaneously rearrange into a monomeric alpha-helix…

nearly all physiological processes are affected by the hormones. They regulate almost all body function starting from metabolism, grow and development as well as water and electrolyte balance, reproduction and human behaviour. This system uses just one method of communication which are a chemical signals which are hormones, where the nervous system uses two: chemical and the electrical…

1. “Clones” A clone is a group (family) of cells which come from a single parent cell that divides various times and are identical in all ways. In their structure, metabolic characteristics, functions, etc. 2.1.2. “Antibodies” An antibody is a protein which is produced by the human body’s immune system when it detects a substance that may be harmful (antigens like: bacteria, viruses, chemicals, parasites, etc). Antibodies are sometimes produced when the immune system mistakenly considers a…

could have negative effects on the cell, and could pose a health threat to the organism. Enzymes proteins that speed up chemical reactions by lowering the activation energy. They do this by acting as a template for substrate orientation, stressing the substrates and stabilizing the transition state, providing a favorable microenvironment, or participating directly in the reaction. All of these methods are implemented by the enzyme binding to the substrate or substrates. Substrates bind…

Ion channels are membrane proteins that selectively allow the permeation of ions into and out of cells (Fig.1a ###image messes with formatting). Some channels have evolved to also sense changes in the electrical potential across a membrane. A potential above a certain voltage will trigger the opening of these ion-conducting pores, releasing large stores of ions across the membrane. These voltage-gated ion channels allow for the generation of electrical stimuli (the firing of neurons via the…

membrane, identifying at least two component macromolecules and describing what their basic function is within the membrane. The eukaryotic plasma membrane is a phospholipids bilayer containing proteins and carbohydrates attached to the proteins and sterols. It is a fluid phospholipids bilayer embedded with proteins and glycoprotein. The phospholipids bilayer is arranged in such a manner that they form the center of the membrane. They also contain sterols, which makes the membrane less permeable…

Aleem Mohammad Stone Bio 2107 Lab 14 Sept. 2015 Accuracy Check of Protein Concentration vs FDA Labels Abstract The issue of food label accuracy is becoming very popular in the United States. The widespread awareness of genetically modified organisms and greater insight about the mass production of food lead to many questions and uncertainty about the labeling of edible products. The US Food and Drug Administration (FDA)’s accuracy in labeling will be tested in this experiment to see whether or…
