The Sensory Significance of Apocarotenoids in Wine: Importance of Carotenoid Cleavage Dioxygenase 1 (CCD1) in the Production of β-Ionone [PDF]
Molecules, 2020 Olfactory cues are key drivers of our multisensory experiences of food and drink. For example, our perception and enjoyment of the flavour and taste of a wine is primarily steered by its aroma.

Transcriptomic and targeted metabolomic insights into carotenoid-mediated color formation in sorghum grains [PDF]
Frontiers in Plant ScienceIntroductionSorghum is a major staple crop in semi-arid regions; however, its generally low grain carotenoid content limits its potential contribution to alleviating vitamin A deficiency.

Structural basis for carotenoid cleavage by an archaeal carotenoid dioxygenase [PDF]
Proceedings of the National Academy of Sciences, 2020 Significance The formation of apocarotenoids by carotenoid cleavage dioxygenases (CCDs) is a critical process for several biological signaling systems. However, the active site determinants directing CCDs to cleave a specific alkene bond within the polyene backbone of carotenoids have remained unclear.

Structural and mechanistic aspects of carotenoid cleavage dioxygenases (CCDs) [PDF]
Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, 2020 Carotenoid cleavage dioxygenases (CCDs) comprise a superfamily of mononuclear non-heme iron proteins that catalyze the oxygenolytic fission of alkene bonds in carotenoids to generate apocarotenoid products. Some of these enzymes exhibit additional activities such as carbon skeleton rearrangement and trans-cis isomerization.

Key Residues for Catalytic Function and Metal Coordination in a Carotenoid Cleavage Dioxygenase. [PDF]
J Biol Chem, 2016 Carotenoid cleavage dioxygenases (CCDs) are non-heme iron-containing enzymes found in all domains of life that generate biologically important apocarotenoids. Prior studies have revealed a critical role for a conserved 4-His motif in forming the CCD iron center.
