Specifically, the positive feedback control mechanism is essential in the ripening of fruits and senescence of flowers. In tomato (Lycopersicon esculentum), there is an upsurge in ethylene production after exposure to exogenous ethylene. This, in turn, activates the activity of 1-Aminocyclopropane -1- Carboxylate Synthase. The role of 1-Aminocyclopropane-1-Carboxylate Synthase with regard to the ripening of fruits was first demonstrated in the year 1991. In this experiment, its role was fully understood in transgenic tomato plants that expressed the protein antisense Ribonucleic acid (RNA). Further experimental studies involving mutagenesis and crystallization of the enzyme, three-dimensional structures as well as amino acid residues have been of core importance in understanding its role. ACC synthase is beneficial in a number of ways including induction of apoptosis by oxidative stress, response to both external stimulus and ethylene. ACC synthase is important in cellular response to iron ions. Additionally, the protein plays a vital role in response to wounding, mechanical stimulus as well as jasmonic acid. This protein is expressed during various developmental and growth stages such as anthesis, leaf senescence, bilateral and globular stage. Within the plant cell, at the molecular level, this enzyme is important in protein binding and is expressed in the flowers, leaf apex, embryo, stem and the leaves (Alexander and Don 2032). ...Download file to see next pagesRead More

How the 22nd amino acid is produced

..., this has revealed the synthesis of the acid. Even though it’s clear now that the amino acid is a product of enzymes involved reaction with two molecules of lysine, it’s important to know that the researchers are investigating if the molecule might be having complexity in its origin. Pyrrolysine is said to be very difficult to find in organisms and currently only a dozen of organisms posses it, interestingly its discovery was made in 2002 as being genetically encoded by methanogens; microbes that produce methane. The fact that it was first identified in the microbe have made the scientists to look back on the genetic code evolution.Pyrrolysine is now among the amino...

High Protein Diets: Metabolic Poison for those with Inborn Errors of Amino Acid Metabolism

...atom. There are 20 commonly occurring AA found in proteins and at least 150 other nonprotein amino acids. Normal turnover of amino acids occurs through a series of enzymatically controlled steps, the first of which is often a deamination or removal of the primary amine group to form the corresponding ?-ketoacid. These compounds are metabolized in a step-wise fashion, ultimately entering the tricarboxylic acid (TCA) cycle, leading to the formation of adenosine triphosphate (ATP). Several AA are intermediaries in the urea cycle. AA are also found as intermediates in the transsulfuration pathway, as well as...

Protein and Amino Acid

...Protein and Amino Acid Proteins are the building blocks of human body and are very essential nutrient. Amino acids and the basic units of proteins and are called the building blocks of protein. In general proteins are obtained food sources, such as meats and other animal products such as eggs, cheese and milk. Proteins are broken down into simpler constituents to make it easily for digestion. Amino acids are critical for the proper functioning of the body. Some of the common functions of proteins include repairing...

...proteins are so important is that they are mad up of amino acids, acids that are necessary for life to function as we know it. While it is true that our bodies can make amino acids by itself, it cannot make all of the amino acids that are needed for life, and must get some of them from the food it consumes. These amino acids thus come from proteins, which should be staples in everybody’s diet. Proteins can come from many different varieties of food, such as meat, egg, grains, and other diary products. These foods are essential to our...

Ing-minske procedure/ amino acid protection/ nucleotide analogues/ stereochemistry/ regioselectivity

...Importance of amino acid protection in synthesizing small peptides: Production of peptides in known as “peptide synthesis”, in organic chemistry. However, these organic compounds contain multiple amino acids which are bound together via “peptide” bonds; also known as amide bonds. Synthesis of peptides involves the coupling of carboxyl group or C-terminus of one amino acid to the amino group or N-terminus of another amino acid. In this process unintended reactions are expected, hence there is always a requirement of protecting groups. Chemical synthesis of peptide starts at the C-terminus of the peptide and ends at the N-terminus. The protecting groups are used to prevent polymerization of amino acids, in which each amino acid... is not...

Structure of human and bovine forms of lactoferricin with 47 and 25 amino acid residues, respectively (Source: Bellamy et al., 1992a). The active peptide of bovine Lf was more effective than the corresponding human Lf peptide against a physiologically diverse range Gram-negative and Gram-positive bacteria. The concentrations of LFcin required to cause complete inhibition of growth depend on the strain and the culture medium used. On the other hand, Pseudomonas fluorescens, Enterococcus faecalis and Bifidobacterium bifidum strains were...

...The recommended dietary allowance (RDA) for protein is 0.8 grams of protein per kilogram of body weight for adults. This means that depending on bodyweight you could need between 46 and 56 grams of protein. If we are active it is recommended that we take 0.4-0.6 grams per pound of body weight. This could drastically increase the amount of protein necessary for an active person. With the various shakes and powders that exist the recommended intake can be substantially boosted based solely on weight and need. Using additional shakes and powders while immediately beneficial to some can have adverse effects for others. Your kidneys have to get rid of the unused...

The Role of Amino Acid R-groups to the Structure and Function of Ligand-Protein Complexes

... The Role of Amino Acid R-groups to the Structure and Function of Ligand-Protein Complexes This paper aims at discussing the molecular structure, the Rf and the binding of various amino acids. The paper discusses also the molecular formula. Introduction There are 20 basic amino acids, which have their molecular structure and bonding. Their rate to front also differs and varies from one amino acid to another. The best procedure used in differentiating amino acids is by determining their rate to front, which is mainly established through the process of chromatography. This process is also distinguished by the intensity of colors on the chromatogram. 1. Amino acid names, molecular weights, Rf values and other data as needed... ...

...Protein Research Protein Research Proteins are complex molecules in the body that perform many vital operations in the body cells. Proteins are made up of micro-amino acids that are required by the body cells for structural formation, functioning and regulation of body tissues and organs( Whitford,2005). Every protein in the body has a unique role ranging from structural support and defense to bodily movement. Proteins are classified according to their body function (Whitford, 2005). Antibodies are specialized proteins that protect the body from foreign invaders in the blood stream, and...

...Protein Q Describe the alanine-glucose cycle. The alanine-glucose cycle is responsible for the exchange of alanine molecule between skeletal muscles and liver. Like glutamine, alanine is a very important resultant of amino acid degradation that is used in the body. Alanine is the product of transamination of pyruvate that happens in the muscles. From the muscles, the alanine is absorbed in the liver where the process of transamination occurs. The process occurs in the presence of alpha-ketoglutarate. This cycle generates pyruvate which enters the gluconeogenesis cycle and glutamate which enters the urea cycle. The enzyme which is required for these processes to occur is alanine...
