Development of In Vitro and In Planta Strategies for Efficient Production of High‐Value Steviol Glycosides

Plant Biotechnology Journal, EarlyView.
ABSTRACT Steviol glycosides (SGs) are a group of sweet‐tasting diterpene glycosides found in Stevia rebaudiana. Production of high‐value SGs, Rebaudioside D (Reb D) and Reb M, is limited by inefficient conversion of Reb A to Reb D and stevioside to Reb E.

Simultaneous Overexpression of FERULOYL‐CoA 6′‐HYDROXYLASE 1 and COUMARIN SYNTHASE Leads to Coumarin‐Enriched Lignin and Improved Saccharification in Greenhouse‐ and Field‐Grown Poplar

Plant Biotechnology Journal, EarlyView.
ABSTRACT The urgent need for renewable resources has increased the interest in woody biomass to manufacture bio‐based products. However, lignin recalcitrance limits the enzymatic conversion of wood into fermentable sugars, posing a major challenge for biomass deconstruction.

Screening of Plant UDP-Glycosyltransferases for Betanin Production in Yeast

Applied Biochemistry and Biotechnology
Abstract To cover the rising demand for natural food dyes, new sources and production methods are needed. Microbial fermentation of nature-identical colours, such as the red pigment betanin, has the potential to be a cost-efficient alternative to plant extraction.

Functional analysis of UDP-sugar: sterol glucosyltransferases [PDF]

Glycosyltransferases (GTs) are essential for the biosynthesis and diversification of many therapeutically important natural products. Of these, UDP-sugar: sterol glucosyltransferases (UGTs) (2.4.1.173) catalyse the synthesis of therapeutically important ...

Novel UDP GalNAc Derivative Structures Provide Insight into the Donor Specificity of Human Blood Group Glycosyltransferase

, 2015
Two closely related glycosyltransferases are responsible for the final step of the biosynthesis of ABO H human blood group A and B antigens. The two enzymes differ by only four amino acid residues, which determine whether the enzymes transfer GalNAc ...

Identification of a Flavonoid Glucosyltransferase Involved in 7-OH Site Glycosylation in Tea plants (Camellia sinensis)

Scientific Reports, 2017
Flavonol glycosides, which are often converted from aglycones in a process catalyzed by UDP-glycosyltransferases (UGTs), play an important role for the health of plants and animals.

Functional Differentiation of Duplicated Flavonoid 3-O-Glycosyltransferases in the Flavonol and Anthocyanin Biosynthesis of Freesia hybrida

Frontiers in Plant Science, 2019
Flavonols and anthocyanins are two widely distributed groups of flavonoids that occurred apart during plant evolution and biosynthesized by shared specific enzymes involved in flavonoid metabolism.

Almost 200 years of anthocyanin research: What we know, what we assume and what remains unknown

Plant Biology, EarlyView.
Nearly 200 years of anthocyanin research reveal a well‐understood anthocyanin biosynthetic pathway. However, there are still open questions regarding its evolution, functions and ecological significance. Abstract Flavonoids are frequently presented as health‐beneficial plant metabolites, and their subclass anthocyanins is best known for striking flower

UDP-Glucose Analogues as Inhibitors and Mechanistic Probes of UDP-Glucose Dehydrogenase

, 2016
UDP-glucose dehydrogenase catalyzes the NAD+-dependent 2-fold oxidation of UDP-glucose to give UDP-glucuronic acid. The putative aldehyde intermediate is not released from the active site and is presumably tightly bound.

Identification and Characterization of a Putative Kaempferol Glucosyltransferase UGT78G3 in Medicago truncatula

Plants
UDP-glycosyltransferases (UGTs) represent a large multigene family that play a central role in glycosylating a highly diverse array of natural products, underscoring their critical importance in various biological processes. However, the functional roles
