Abstract EN
Carotenoid cleavage dioxygenases (CCDs) are a group of enzymes that catalyze the oxidative cleavage steps from carotenoids to various carotenoid cleavage products.
Some ccd genes have been identified and encoded enzymes functionally characterized in many higher plants, but little in cyanobacteria.
We performed a comparative analysis of ccd sequences and explored their distribution, classification, phylogeny, evolution, and structure among 37 cyanobacteria.
Totally 61 putative ccd sequences were identified, which are abundant in Acaryochloris marina MBIC 11017, filamentous N2-fixing cyanobacteria, and unicellular cyanobacterial Cyanothece.
According to phylogenetic trees of 16S rDNA and CCD, nced and ccd8 genes occur later than the divergence of ccd7, apco, and ccd1.
All CCD enzymes share conserved basic structure domains constituted by a single loop formed with seven β-strands and one helix.
In this paper, a general framework of sequence-function-evolution connection for the ccd has been revealed, which may provide new insight for functional investigation.
