Either monoamine oxidase A (MAO) or catechol-O-methyltransferase (COMT) can catalyze the first step in catecholamine catabolism. The potentially toxic aldehyde intermediate generated in the MAO reaction (3,4-dihydroxyphenylacetaldehyde for dopamine, 3,4-dihydroxyphenylglycolaldehyde for norepinephrine) is either rapidly reduced to an alcohol (by
A form of synthetic biology, cell-free protein synthesis or expression (CFPE) is a rapid method to produce recombinant proteins in solution without involving cells. Using biomolecular translation machinery extracted from a range of different cell types, researchers can express a
The search for a functional thrombin receptor, using expression cloning methods, led to the discovery of a G protein-coupled receptor that mediates the actions of thrombin on platelets and endothelial cells.
Proteins are complex biological molecules essential for cellular structure and functions. The majority of proteins commonly interact with various molecules, including other proteins, in order to exert their functions.
Protein synthesis is a complex, multi-step process involving many enzymes as well as conformational alignment. However, the majority of antibiotics that block bacterial protein synthesis interfere with the processes at the 30S subunit or 50S subunit of the 70S bacterial
Protein tyrosine phosphatases (PTPs) and related enzymes (more than a hundred coded by the human genome) are more numerous than serine/threonine phosphatases. They belong to four families, three of which possess a conserved cysteine for catalysis and some conserved features
