Betalain biosynthesis of amino

  • 15.04.2019
While more enzymology is celebrated, it is possible that only a few other acid changes underpin the functional parents. Only PmDOD was bad in betalain synthesis expected on amino assays of enzyme teller and correlation of transcript abundance to spatio-temporal betalain oak. Betaxanthins represent another subclass of betalains. One biosynthesis intermediate in this biosynthesis is cyclo-DOPA that is also a short for the further furnishing of betalains.

TIF pone. Amino acids that appear to differentiate the three primary groups resolved in the gene tree are highlighted. DOC pone. Furthermore, as some betalain taxa also produce some of these other metabolites e.

The red betacyanic transgenic tobacco plants also contained betaxanthin. By contrast, betalainic species are capable of making betacyanins without concomitant betaxanthin production. More extensive characterization of the biosynthetic enzyme activities will provide a foundation for understanding this elegant control and applying it to engineering efforts. Also, the plant physiologists among us will be excited by the possibilities generated through engineering for investigating betalain functions in more tractable plant systems or for conducting comparative functional studies of betalains and anthocyanins.

Plants could also be made that produce both types of pigment to address whether a fitness cost led to them never being retained in the same species. Betaxanthin It has been demonstrated that the conjugation of a broad variety of amino acids see betaxanthin biosynthesis via dopaxanthin and amino acid derivatives e. The first enzymatic step in the pathway is the decarboxylation of aromatic amino acids such as tyrosine or DOPA to form the corresponding amines tyramine and dopamine, respectively [ Facchini94a , Facchini95a ].

Tyrosinases have also been described as capable to use certain betaxanthins [ GandiaHerrero05b ] as substrates for further metabolization.

From those results, an alternative pathway has been proposed for the formation of betanidin which involves a tyrosinase activity that converts dopaxanthin into dopaxanthinquinone.

Dopaxanthinquinone is than spontaneously cyclisized into betanidin [ GandiaHerrero05a ]. A similar approach has been undertaken to delineate alternative metabolism for the formation of 2-descarboxy-betanidin compare betacyanin biosynthesis via dopamine by acting of those tyrosinases on the amine-derived intermediates such as dopamine-betaxanthin to produce the corresponding quinone [ GandiaHerrero05 ].

However, as neither family are basal to the betalain families, and Molluginaceae actually resides within the betalain lineages, the betalain families are not monophyletic Cuenoud et al.

The biosynthetic and regulatory pathway for betalain production has also not been fully characterized. Until recently, only one of the enzymes responsible for formation of the colored compounds had been characterized at the molecular genetic level, dopa 4,5-dioxygenase DOD. However, recent breakthroughs for Beta vulgaris beet have identified a gene for a second biosynthetic step Hatlestad et al.

Betalains are stored in the vacuole and betacyanins are normally stored as glycosides, with glucosylation possible at either the betanidin or cyclo-DOPA steps of the biosynthetic pathway Strack et al. Betacyanin DOPA may be synthesized through two different pathways from L-tyrosine involving either a bifunctional tyrosinase [ Steiner99 ] or a tyrosine hydroxylase that requires pteridin cofactors for its activity, the latter representing a new enzyme reported for this reaction [ Yamamoto01a ]. The glucosylation of betanidin takes place in a regiospecific way resulting in either the production of betanin via betanidin 5-O-glucosyltransferase [ Vogt99 ] or e. One crucial intermediate in this biosynthesis is cyclo-DOPA that is also a precursor for the further furnishing of betalains.

This article has been cited by other articles in PMC. These advances broaden the scope of the questions that can be answered about betalain production and function and open up the biotechnological possibilities. The tree presented here is very similar to that presented by Brockington et al. Only betacyanins contain a glucose moiety that may be further furnished with other molecules such as malonylate and hydroxycinnamic acids. However, no proof regarding either type of enzyme for betalains has been obtained, despite use of powerful transcriptomics approaches that have come to the fore in recent years for elucidating metabolite pathways. Intriguingly, there are a few families Caryophyllaceae and Molluginaceae within the core Caryophyllales that produce the more common, and extensively studied, anthocyanin pigments.
