A recombinant form of geraniol dehydrogenase (EC 1.1.1.183) from Backhousia citriodora was overexpressed in Escherichia coli and purified and crystallized by the sitting-drop method using polyethylene glycol 3350 as a precipitant. A data set to 2.3 Å resolution was collected from a monocrystal at 98 K using synchrotron radiation on beamline NE3A of the Photon Factory. The crystals belonged to the orthorhombic group P2(1)2(1)2, with unit-cell parameters a = 125.00, b = 151.01, c = 51.18 Å. The asymmetric unit is expected to contain two BcGEDH molecules, with a corresponding crystal volume per protein weight of 3.1 Å(3) Da(-1) and a solvent content of 60.6%.

()-Citronellal is a key chiral precursor of high-value chemicals, such as the best-selling flavor compound (-)-menthol; however, the conventional synthesis suffers from low yield and unsatisfactory enantioselectivity. In this study, we developed a highly atom-efficient hydrogen-borrowing cascade for the synthesis of ()-citronellal from geraniol using alcohol dehydrogenase from K12 (AdhP) and ene-reductase from YJM1341 (OYE2p). The key rate-limiting enzyme, AdhP, was subjected to structure-guided semirational engineering, and the triple mutant AdhP (M3) was obtained that demonstrated a 1.

Citral, a naturally occurring acyclic monoterpene aldehyde, is present in the essential oils of various plants, but only a few produce it in abundance. Despite its importance as a key aroma molecule, knowledge regarding the in-planta biosynthesis of citral and its metabolic origin remains limited. Here, we have elucidated the functions of an alcohol dehydrogenase (CfADH1) and an aldoketo-reductase (CfAKR2b) in citral biosynthesis in lemongrass (Cymbopogon flexuosus), one of the most cultivated aromatic crops for its citral-rich essential oil.

The fascinating scent of rose (Rosa genus) flowers has captivated human senses for centuries, making them one of the most popular and widely used floral fragrances. Despite much progress over the last decade, many biochemical pathways responsible for rose scents remain unclear. We analyzed the floral scent compositions from various rose varieties and selected the modern cultivar Rosa hybrida "Double Delight" as a model system to unravel the formation of rose dominant volatile terpenes, which contribute substantially to the rose fragrance.

Chardonnay is one of the most popular white grape wine varieties in the world, but this wine lacks typical aroma, considered a sensory defect. Our research group identified a Chardonnay bud sport with typical muscat characteristics. The goal of this work was to discover the key candidate genes related to muscat characteristics in this Chardonnay bud sport to reveal the mechanism of muscat formation and guide molecular design breeding.

The citral-type is the most common chemotype in Cinnamomum bodinieri Levl (C. bodinieri), which has been widely used in the daily necessities, cosmetics, biomedicine, and aromatic areas due to their high citral content. Despite of this economic prospect, the possible gene-regulatory roles of citral biosynthesis in the same geographic environment remains unknown.
