PHOSPHOGLUCONATE DEHYDROGENASE Meaning and Definition

1. Phosphogluconate dehydrogenase (PGD) is an enzyme involved in the metabolic pathway known as the pentose phosphate pathway (PPP) or the hexose monophosphate shunt. It catalyzes the oxidation of 6-phosphogluconate (6-PG) to ribulose-5-phosphate (Ru5P), thus producing NADPH (reduced nicotinamide adenine dinucleotide phosphate) and carbon dioxide. This reaction is an essential step in the PPP, which produces NADPH for various cellular processes, such as fatty acid and nucleotide biosynthesis, as well as maintaining the reducing power of the cell.

   Phosphogluconate dehydrogenase is predominantly found in the cytosol of cells, particularly in tissues with high rates of biosynthesis and oxidative metabolism, such as the liver, adipose tissue, and adrenal cortex. The enzyme is typically a homodimer consisting of two identical subunits, with each subunit containing an active site for the catalytic reaction.

   The activity of phosphogluconate dehydrogenase is regulated by various factors, including allosteric effectors like NADPH, which serves as a negative feedback inhibitor, and 6-phosphogluconolactone, which acts as a positive effector. This ensures the tight control of NADPH levels within the cell. Deficiency or mutations in phosphogluconate dehydrogenase can lead to metabolic disorders, such as glucose-6-phosphate dehydrogenase deficiency, which is characterized by impaired PPP activity and reduced NADPH production, leading to oxidative stress and hemolytic anemia.

   In summary, phosphogluconate dehydrogenase is an important enzyme

Etymology of PHOSPHOGLUCONATE DEHYDROGENASE

The word "Phosphogluconate Dehydrogenase" has the following etymology:

1. Phospho-: A prefix indicating the presence of a phosphate group in the molecule. It comes from the Greek word "phosphoros", meaning "light-bringing".

2. Gluconate: A compound derived from glucose. The term "gluco-" derives from the Greek word "glykys", meaning "sweet".

3. Dehydrogenase: A suffix indicating an enzyme that catalyzes the removal of hydrogen from a molecule. It comes from the Greek words "dehydro", meaning "lost hydrogen", and "genēs", meaning "producer" or "generator".

Therefore, "Phosphogluconate Dehydrogenase" refers to an enzyme that removes hydrogen from a phosphogluconate molecule, which is derived from glucose.
