of single-stranded DNA cytosine residues in aerobic nitric oxide solution at micromolar total NO exposures.
effective nucleophilicity, and cage effects in deamination
To our knowledge, no studies have calibrated the rate at which different tissues become enriched in 15N as a function of their rates of mass loss, protein catabolism, and deamination
(see Bond and Barrett 1993).
The alkaline pH is suitable for deamination
reactions leading to the release of ammonium which increases pH and this increase in pH favors keratinolysis (Riffel et al., 2003).
Bryan and Olafsson  state that the main decomposition reaction is decarboxylation, possibly preceded by deamination
. Weiss et al.
The search algorithm Sequest HT was used with the following parameters: precursor mass tolerance: 20 ppm; fragment mass tolerance: 0.05 Da; and dynamic modifications of oxidation on M and deamination
on N and Q.

It turns out that a very common form of DNA mutation can arise due to spontaneous hydrolytic deamination
of cytosine, where its amine is displaced by an oxygen--in fact turning it into a uracil.
[7,8] ADA is an enzyme of purine catabolism leading to hydrolytic deamination
of adenosine to inosine and ammonia.
MAOs employ a FAD cofactor to catalyze the oxidative deamination
of several monoamines, including not only neurotransmitters (e.g., serotonin, norepinephrine, and dopamine) but also exogenous amines ingested with normal diets (tyramine), generating [H.sub.2][O.sub.2] and the corresponding aldehydes as by-products (Figure 1).
Other biochemical reactions included deamination
of arginine, pigment production, motility determination and tellurite reduction.
 Moreover, there are data suggesting altered peripheral noradrenalin deamination
and/or uptake in adolescent patients with PCOS.
These higher alcohols are mostly produced from the deamination
of nitrogen from amino acids, for example, arginine, which has a free [alpha]-amino group.
The following search parameters were used in all of the Sequest searches: Maximum of 2 missed trypsin cleavages, cysteine carbamidomethylation as a fixed modification, methionine oxidation and N/Q deamination
as the variable modification.
These bacterial species are the main responsible for amino acid deamination
and produce unwanted gases, such as methane and ammonia.
