Deamination is the removal of an amino group from a molecule. [1] Enzymes that catalyse this reaction are called deaminases. In the human body, deamination takes place primarily in the liver; however, it can also occur in the kidney. In situations of excess protein intake, deamination is used to break down amino acids for energy.

Oxidative deamination is the first step to breaking down the amino acids so that they can be converted to sugars. The process begins by removing the amino group of the amino acids. The amino group becomes ammonium as it is lost and later undergoes the urea cycle to become urea, in the liver. It is then released into the blood stream, where it ...
Oxidative deamination is a form of deamination that generates α-keto acids and other oxidized products from amine-containing compounds, and occurs primarily in the liver. [1] Oxidative deamination is stereospecific, meaning it contains different stereoisomers as reactants and products; this process is either catalyzed by L or D- amino acid ...
Cytidine deaminase is an enzyme that in humans is encoded by the CDA gene. [5] [6] [7]This gene encodes an enzyme involved in pyrimidine salvaging. The encoded protein forms a homotetramer that catalyzes the irreversible hydrolytic deamination of cytidine and deoxycytidine to uridine and deoxyuridine, respectively.
As suggested by the name of the family, LAAOs are flavoenzymes which function to catalyze the stereospecific oxidative deamination of an L-amino acid. [4] The three substrates of the enzymatic reaction are an L-amino acid, water, and oxygen, whereas the three products are the corresponding α-keto acid (2-oxo acid), ammonia, and hydrogen peroxide.
The deamination of adenosine to inosine disrupts and destabilizes the dsRNA base pairing, therefore rendering that particular dsRNA less able to produce siRNA, which interferes with the RNAi pathway. The wobble base pairing causes deaminated RNA to have a unique but different structure, which may be related to the inhibition of the initiation ...
They often arise by oxidative deamination of amino acids, and reciprocally, they are precursors to the same. Alpha-keto acids possesses extensive chemistry as acylation agents. [3] Furthermore, alpha-keto acids such as phenylpyruvic acid are endogenous sources for carbon monoxide (as a gasotransmitter) and pharmaceutical prodrug scaffold. [4]
