Characterization of Transcriptional Expression and Regulation of Carotenoid Cleavage Dioxygenase 4b in Grapes [PDF]

Frontiers in Plant Science, 2020
Norisoprenoids are important aromatic volatiles contributing to the pleasant floral/fruity odor in grapes and wine. They are produced from carotenoids through the cleavage of carotenoid cleavage dioxygenases (CCDs).

Selective inhibition of carotenoid cleavage dioxygenases: phenotypic effects on shoot branching. [PDF]

J Biol Chem, 2009
Members of the carotenoid cleavage dioxygenase family catalyze the oxidative cleavage of carotenoids at various chain positions, leading to the formation of a wide range of apocarotenoid signaling molecules. To explore the functions of this diverse enzyme family, we have used a chemical genetic approach to design selective inhibitors for different ...

Cloning and Prokaryotic Expression of Carotenoid Cleavage Dioxygenases from Mulberry (Morus notabilis). [PDF]

Evid Based Complement Alternat Med, 2022
Carotenoid cleavage dioxygenase (CCD) is the key enzyme for carotenoid cleavage, and the products of carotenoid cleavage regulate the ability of plants to stress. In this paper, six CCD genes were obtained from Morus notabilis (Mn) by reverse transcription-polymerase chain reaction (RT-PCR) and we classified them into three subgroups based on gene ...

Genomewide analysis of carotenoid cleavage dioxygenases in unicellular and filamentous cyanobacteria. [PDF]

Comp Funct Genomics, 2012
Carotenoid cleavage dioxygenases (CCDs) are a group of enzymes that catalyze the oxidative cleavage steps from carotenoids to various carotenoid cleavage products. Someccdgenes have been identified and encoded enzymes functionally characterized in many higher plants, but little in cyanobacteria.

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.

Genome-wide identification and in-silico expression analysis of carotenoid cleavage oxygenases gene family in Oryza sativa (rice) in response to abiotic stress

Frontiers in Plant Science, 2023
Rice constitutes a foundational cereal and plays a vital role in the culinary sector. However, the detriments of abiotic stress on rice quality and productivity are noteworthy. Carotenoid cleavage oxygenases (CCO) hold vital importance as they enable the

On the substrate‐ and stereospecificity of the plant carotenoid cleavage dioxygenase 7 [PDF]

FEBS Letters, 2014
Strigolactones are phytohormones synthesized from carotenoids via a stereospecific pathway involving the carotenoid cleavage dioxygenases 7 (CCD7) and 8. CCD7 cleaves 9‐cis‐β‐carotene to form a supposedly 9‐cis‐configured β‐apo‐10′‐carotenal. CCD8 converts this intermediate through a combination of yet undetermined reactions into the strigolactone‐like

Carotenoid Cleavage Dioxygenases: Identification, Expression, and Evolutionary Analysis of This Gene Family in Tobacco. [PDF]

Int J Mol Sci, 2019
Carotenoid cleavage dioxygenases (CCDs) selectively catalyze carotenoids, forming smaller apocarotenoids that are essential for the synthesis of apocarotenoid flavor, aroma volatiles, and phytohormone ABA/SLs, as well as responses to abiotic stresses.

Characterization of a Novel Carotenoid Cleavage Dioxygenase from Plants [PDF]

Journal of Biological Chemistry, 2001
The plant hormone abscisic acid is derived from the oxidative cleavage of a carotenoid precursor. Enzymes that catalyze this carotenoid cleavage reaction, nine-cis epoxy-carotenoid dioxygenases, have been identified in several plant species. Similar proteins, whose functions are not yet known, are present in diverse organisms.
