Abstract
To study the presence of diamine oxidase (DAO) activity in any tissue with putrescine as the substrate, it is necessary to use inhibitors to block all pathways that could further metabolize gamma-aminobutyraldehyde, which is the product of enzyme reaction. It is also necessary to inhibit any enzyme that may convert putrescine into higher polyamines. By this approach it was observed that lung tissue of both rat and rabbit exhibited no DAO activity. DAO activity was observed in the rat and rabbit intestine, the former showing 3 times as much activity as the latter. The other potential pathways of putrescine metabolism are of no consequence in the rat and rabbit intestine and lungs.Entities:
