putrescine catabolic process
Definition
Target type: biologicalprocess
The chemical reactions and pathways resulting in the breakdown of putrescine, 1,4-diaminobutane; putrescine is the metabolic precursor of spermidine and spermine. [GOC:ai]
Putrescine catabolic process is the metabolic breakdown of putrescine, a polyamine that plays a significant role in various cellular processes, including cell growth, differentiation, and proliferation. The process begins with the oxidation of putrescine by the enzyme diamine oxidase (DAO), which converts it to 4-aminobutylaldehyde. This aldehyde is then further oxidized by the enzyme aldehyde dehydrogenase to γ-aminobutyric acid (GABA), a neurotransmitter. The breakdown of putrescine can occur in various cellular compartments, including the cytoplasm, mitochondria, and peroxisomes. The catabolism of putrescine is tightly regulated and is influenced by factors such as dietary intake, hormonal levels, and cellular stress. Disruptions in putrescine catabolism can contribute to various pathological conditions, including cancer, neurodegenerative diseases, and inflammatory disorders.'
