Nocardicin-A epimerase
Encyclopedia
In enzymology, a nocardicin-A epimerase is an enzyme
that catalyzes
the chemical reaction
Hence, this enzyme has one substrate
, isonocardicin A, and one product
, nocardicin A
.
This enzyme belongs to the family of isomerase
s, specifically those racemases and epimerases acting on amino acid
s and derivatives. The systematic name of this enzyme class is nocardicin-A epimerase. This enzyme is also called isonocardicin A epimerase.
Enzyme
Enzymes are proteins that catalyze chemical reactions. In enzymatic reactions, the molecules at the beginning of the process, called substrates, are converted into different molecules, called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates...

Catalysis
Catalysis is the change in rate of a chemical reaction due to the participation of a substance called a catalyst. Unlike other reagents that participate in the chemical reaction, a catalyst is not consumed by the reaction itself. A catalyst may participate in multiple chemical transformations....
the chemical reaction
Chemical reaction
A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Chemical reactions can be either spontaneous, requiring no input of energy, or non-spontaneous, typically following the input of some type of energy, such as heat, light or electricity...

Substrate (biochemistry)
In biochemistry, a substrate is a molecule upon which an enzyme acts. Enzymes catalyze chemical reactions involving the substrate. In the case of a single substrate, the substrate binds with the enzyme active site, and an enzyme-substrate complex is formed. The substrate is transformed into one or...

Product (chemistry)
Product are formed during chemical reactions as reagents are consumed. Products have lower energy than the reagents and are produced during the reaction according to the second law of thermodynamics. The released energy comes from changes in chemical bonds between atoms in reagent molecules and...

Nocardicin A
Nocardicin A is a β-lactam antibiotic included in the monobactam subclass. It is secreted by the bacterium Nocardia uniformis subsp. tsuyamenensis as a metabolic product catalyzed by the enzyme nocardicin-A epimerase....

Isomerase
In biochemistry, an isomerase is an enzyme that catalyzes the structural rearrangement of isomers. Isomerases thus catalyze reactions of the formwhere B is an isomer of A.-Nomenclature:...

Amino acid
Amino acids are molecules containing an amine group, a carboxylic acid group and a side-chain that varies between different amino acids. The key elements of an amino acid are carbon, hydrogen, oxygen, and nitrogen...
