Dimethylaniline-N-oxide aldolase
Encyclopedia
In enzymology, a dimethylaniline-N-oxide aldolase is an enzyme
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...

 that catalyzes
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...


N,N-dimethylaniline N-oxide N-methylaniline + formaldehyde


Hence, this enzyme has one substrate
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...

, N,N-dimethylaniline N-oxide, and two products
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...

, N-methylaniline
N-methylaniline
N-Methylaniline is an aniline derivative. It is a toxic organic compound with the chemical formula C6H5NH. The substance exists as a colorless or slightly yellow viscous liquid, which is insoluble in water and brown when exposed to air...

 and formaldehyde
Formaldehyde
Formaldehyde is an organic compound with the formula CH2O. It is the simplest aldehyde, hence its systematic name methanal.Formaldehyde is a colorless gas with a characteristic pungent odor. It is an important precursor to many other chemical compounds, especially for polymers...

This enzyme belongs to the family of lyase
Lyase
In biochemistry, a lyase is an enzyme that catalyzes the breaking of various chemical bonds by means other than hydrolysis and oxidation, often forming a new double bond or a new ring structure...

s, specifically the aldehyde-lyases, which cleave carbon-carbon bonds. The systematic name of this enzyme class is N,N-dimethylaniline-N-oxide formaldehyde-lyase (N-methylaniline-forming). Other names in common use include microsomal oxidase II, microsomal N-oxide dealkylase, and N,N-dimethylaniline-N-oxide formaldehyde-lyase.
