Upon further spectroscopic characterization and investigation of the substrate pool of this enzyme, Dr. Ziegler discovered that this enzyme solely bound FAD molecule that could form a C4a-hydroxyperoxyflavin intermediate, and that this enzyme could oxidize a wide variety of substrates with no common structural features, including phosphines ...
Its role in sugar metabolism has been studied extensively in plants in order to understand plant growth and increase agricultural production. Recently, human UTP—glucose-1-phosphate uridylyltransferase has been studied and crystallized, revealing a different type of regulation than other organisms previously studied.
Exocrine pancreatic insufficiency (EPI) is the inability to properly digest food due to a lack or reduction of digestive enzymes made by the pancreas.EPI can occur in humans and is prevalent in many conditions [1] such as cystic fibrosis, [2] Shwachman–Diamond syndrome, [3] different types of pancreatitis, [4] multiple types of diabetes mellitus (Type 1 and Type 2 diabetes), [5] advanced ...
Inborn errors of metabolism are often referred to as congenital metabolic diseases or inherited metabolic disorders. [2] Another term used to describe these disorders is "enzymopathies". This term was created following the study of biodynamic enzymology , a science based on the study of the enzymes and their products.
Beyond β-glucosidases expressed in human tissues, bacterial β-glucosidases are also found in human saliva and inside the intestine produced by the bacterial microbiota of the mouth and gastro-intestinal tract, with various implications to normal human health, drug and hormone metabolism, and involvement in certain diseases.
NADPH oxidase (nicotinamide adenine dinucleotide phosphate oxidase) is a membrane-bound enzyme complex that faces the extracellular space. It can be found in the plasma membrane as well as in the membranes of phagosomes used by neutrophil white blood cells to engulf microorganisms.
The biochemical pathways required to utilize glucose as a carbon and energy source are highly conserved from bacteria to humans. PGM1 is an evolutionarily conserved enzyme that regulates one of the most important metabolic carbohydrate trafficking points in prokaryotic and eukaryotic organisms, catalyzing the bi-directional interconversion of glucose 1-phosphate (G-1-P) and glucose 6-phosphate ...
Protoporphyrinogen oxidase or protox is an enzyme that in humans is encoded by the PPOX gene. [5] [6] [7] Protoporphyrinogen oxidase is responsible for the seventh step in biosynthesis of protoporphyrin IX. This porphyrin is the precursor to hemoglobin, the oxygen carrier in animals, and chlorophyll, the dye in plants.
