An enzyme that hydrolizes a molecule of inorganic pyrophosphate to yield two molecules of (ortho) phosphate; also known as pyrophosphatase
|
inorganic pyrophosphatase
|
|

Covalent attachment of the adenylyl group (AMP) to some protein or small molecule.
|
adenylylation
|
|
|
An ester of carboxylic acid with a thiol or mercaptan

The phase of intermediary metabolism concerned with the energy requiring biosynthesis of cell components from smaller precursors.
|
anabolism
|
|
|
The phase of intermediary matabolism concerned with the energy yielding degradation of nutrient molecules.
|
catabolism
|
|
|
In cells, the enzyme-catalyzed reactions that extract chemical energy from nutrient molecules and utilize it to synthesize and assemble cell components.
|
intermediary metabolism
|
|
|
A chemical intermediate in the enzyme-catalyzed reactions of metabolism
|
metabolite
|
|
|
The entire set of enzyme-catalyzed transformations of organic molecules in living cells; the sum of anabolism and catabolism.
|
metabolism
|
|
|
An organism that requires complex nutrient molecules, such as glucose, as a source of energy and carbon.
|
heterotroph
|
|
|
An organism that can synthesize its own complex molecules from very simple carbon and nitrogen sources, such as carbon dioxide and ammonia.
|
autotroph
|
