Coding sequence for 4,5-DODA enzyme

Description

Betalains are water-soluble nitrogen-containing pigments that are subdivided in red-violet betacyanins and yellow-orange betaxanthins. Due to glycosylation and acylation betalains exhibit a huge structural diversity. Betanin (betanidin-5-O--glucoside) is the most common betacyanin in the plant kingdom. The biosynthesis of betalains in plants excludes that of anthocyanins. During the biosynthesis of betalains in the cytoplasm three enzymes are involved: Tyrosinase, 4,5-DOPA-extradioldioxygenase, and betanidin-glucosyltransferase. The amino acid L-tyrosine, which is enzymatically formed over the shikimate pathway from arogenic acid, is the precursor for the biosynthesis of L-DOPA. Tyrosine is hydroxylated by means of the enzyme tyrosinase to DOPA (I) that is formed to betalamic acid or to cyclo-DOPA. The biosynthesis of betalamic acid, which is the basic structure of betalains as follow: 4,5-DOPA-extradiol dioxygenase opens the cyclic ring of L-DOPA between carbons 4 and 5, thus producing 4,5-seco-DOPA (II). This intermediate product occurs naturally. Due to spontaneous intramolecular condensation between the amine group and the aldehyde group of 4,5-seco-DOPA betalamic acid is formed. In order to make the production of the Betacyanin much efficient, Shanghai_SFLS_SPBS successfully change the RBS and makes it express in the E.coli and Vibrio natriegens.
