Ammonia arises from the impaired buffering of ADP, which leads to an increase in AMP concentration resulting in an increase in AMP deamination.
42.
Amino acids that are excess to requirement cannot be stored, but must be modified by deamination ( removal of the amine group ).
43.
Adenosine monophosphate deaminase 1 catalyzes the deamination of AMP to IMP in skeletal muscle and plays an important role in the purine nucleotide cycle.
44.
While spontaneous deamination of cytosine forms uracil, which is recognized and removed by DNA repair enzymes, deamination of 5-methylcytosine forms thymine.
45.
While spontaneous deamination of cytosine forms uracil, which is recognized and removed by DNA repair enzymes, deamination of 5-methylcytosine forms thymine.
46.
The predicted deamination reaction is driven by a direct nucleophilic attack on position 4 of the cytidine pyrimidine ring by the zinc-coordinated enzyme.
47.
For the removal of lymphnodes, the deamination rate in the liver may decrease . talk ) 18 : 40, 27 July 2008 ( UTC)
48.
In addition an excess of deamination and conversion of cytosine to thymine in the coding strand compared to the non-coding strand has been reported.
49.
Two proposed mechanisms exist for ADA-catalyzed deamination : 1 ) stereospecific addition-elimination via tetrahedral intermediate or 2 ) an S N 2 reaction.
50.
The major step in the methylation cycle is the remethylation of homocysteine, a compound which is naturally generated during deamination of the essential amino acid methionine.
