PAAS-Petunia

Petunia hybrida cv. Mitchell hybrid phenylacetaldehyde synthase (PAAS) is capable of transforming L-phenylalanine (L-phe) into phenylacetaldehyde by oxidative decarboxylation. Subsequently, phenylacetaldehyde can be reducted into phenylethanol, which possesses elegant, fascinating and long-lasting fragrance.

-Petunia hybrida cv. Mitchell phenylacetaldehyde synthase (PAAS) can catalyze the formation of phenylacetaldehyde, a constituent of floral scent. PAAS is a cytosolic homotetrameric enzyme that belongs to group II pyridoxal 5'-phosphate-dependent amino-acid decarboxylases and shares extensive amino acid identity (~65%) with plant L-tyrosine/3,4-dihydroxy-L-phenylalanine and L-tryptophan decarboxylases. It displays a strict specificity for phenylalanine with an apparent Km of 1.2mM. PAAS is a bifunctional enzyme that catalyzes the unprecedented efficient coupling of phenylalanine decarboxylation to oxidation, generating phenylacetaldehyde, CO2, ammonia, and hydrogen peroxide in stoichiometric amounts.
