The end product of lysine decarboxylation
WebJan 21, 2010 · Introduction. 3,4-Dihydroxyphenylalanine (DOPA) decarboxylase (DDC) is a pyridoxal-5′-phophate (PLP)-dependent enzyme which physiologically catalyzes the decarboxylation of 3,4-dihydroxyphenylalanine to dopamine, and 5-hydroxytryptophan (5-HTP) to 5-hydroxytryptamine (serotonin) , .Because the enzyme catalyzes the … WebJul 19, 2005 · Function. Inducible lysine decarboxylase that catalyzes the proton-dependent decarboxylation of L-lysine to produce the polyamine cadaverine and carbon dioxide ( PubMed: 4590109 ). Plays a role in pH homeostasis by consuming protons and neutralizing the acidic by-products of carbohydrate fermentation ( PubMed: 17209032 ).

The culture is incubated an additional 24 hours at 35-37 C to allow the microbe to now use the lysine. The final results are then obtained by observing the tube at 48 hours. Change back to purple from yellow indicates a positive test for lysine decarboxylase.
WebLIA slants contain lysine, glucose, peptones, bromcresol purple (pH indicator), sodium thiosulfate and ferric ammonium citrate. If the organism has the ability to decarboxylate lysine, it produces an amine end-product which reacts with the pH indicator to give a purple color in the butt of the tube. (Negative decarboxylation: yellow butt). http://www.dalynn.com/dyn/ck_assets/files/tech/TL97.pdf
