The 3 … WebMay 30, 2024 · The enzymes involved in the oxidative deamination of PAs are diamine oxidases (DAO) and polyamine oxidase (PAO), both of them catalyze Put, Spd and Spm to 4-aminobutyraldehyde (ABAL) and aminoaldehyde dehydrogenase (AMADH) thereafter to produce GABA [17,18]. Information about GABA accumulation in watercore fruit is limited.
http://www.eagri.org/eagri50/BIC101/pdf/lec28.pdf WebThen, glutamate can be deaminated to produce ammonia (from the original amino acid) that is cleared through the urea cycle and excreted. Since glutamate is the product of many transamination reactions, it is the main substrate for oxidative deamination (by GDH in liver and other tissues). The GDH reaction is
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. Oxidative deamination is stereospecific, meaning it contains different stereoisomers as reactants and products; this process is either catalyzed by L or D- amino acid oxidase and L-amino acid oxidase is present only in the liver and kidney. Oxidative deamination is an important step in the cataboli…
