Pyridoxal phosphate Pyridoxal phosphate (PLP, pyridoxal 5'- phosphate, P5P), the active form of vitamin B6, is a coenzyme in a variety of enzymatic reactions.nimals are auxotrophs for this enzyme co-factor and require it or an intermediate to be supplemented, hence its classification as a vitamin B 6, unlike MoCo or CoQ10 for example. PLP is synthesized from pyridoxal by the enzyme pyridoxal kinase, requiring one ATP molecule. PLP is metabolized in the liver.

Adenosine diphosphate Energy transfer used by all living things is a result of dephosphorylation of ATP by enzymes known as ATPases. The cleavage of a phosphate group from ATP results in the coupling of energy to metabolic reactions and a by-product, a molecule of ADP.he two phosphate groups of ADP are added in series to the 5’ carbon of the sugar backbone, while the adenosine molecule attaches to the 1’ carbon.

Explain how ATP production is controlled by the cell and what role the allosteric enzyme, phosphofructokinase,? fructose-6-phosphate + ATP fructose-1,6-bisphosphate + ADP. In part because of the irreversible nature of this step in glycolysis, PFK is the key regulatory enzyme for glycolysis. When ATP levels are high in the cell, the cell no longer needs metabolic energy production to occur.

- Phytase. Phytase is an enzyme that specifically acts on phytate, breaking it down to release phosphorus in a form available to the animal. This greatly reduces the need for supplemental inorganic phosphorus and improves the nutritional value of feedstuffs.ast facts. Phytase is an enzyme that increases availability of phosphorus in pig diets. Phytase lowers the amount of supplemental phosphorus required in the diet. Because of improved dietary phosphorus utilization, less phosphorus is excreted in the manure.

- Like PFK, pyruvate kinase is regulated both by allosteric effectors and by covalent modification (phosphorylation). Pyruvate kinase is activated by F-1,6-BP in the liver, a second example of feedforward stimulation. ATP and alanine (a biosynthetic product of pyruvate) act as allosteric inhibitors of pyruvate kinase.

- In the liver, the action of glucokinase is opposed by the action of glucose-6-phosphatase, which hydrolytically removes phosphate in a futile cycle. At normal levels of blood glucose (5 mM), the forward and back reactions are balanced. This is wasteful of ATP, but helps the liver to buffer blood glucose concentrations.

G6PD gene This enzyme helps protect red blood cells from damage and premature destruction. Glucose-6-phosphate dehydrogenase is responsible for the first step in a chemical pathway that converts glucose (a type of sugar found in most carbohydrates) to ribose-5-phosphate.ibose-5-phosphate is an important component of nucleotides, which are the building blocks of DNA and its chemical cousin RNA. This chemical reaction produces a molecule called NADPH, which plays a role in protecting cells from potentially harmful molecules called reactive oxygen species.
