Abstract: The phytoene desaturase is a key enzyme involved in the carotenoids biosynthesis pathway,
which catalyzes the conversion of ζ-carotene from phytoene. Undaria pinnatifida Suringar is an edible
economic brown algae that produces high concentrations of fucoxanthin. In this study, the PDS gene
(UpPDS) was isolated and characterized from U. pinnatifida, and the full-length cDNA sequence was
1707 bp in length and encoded 568 amino acid residues. Furthermore, the putative protein sequence
showed a high homology to the PDS from other known plants. Phylogenetic analysis showed that
the UpPDS was more related to that of brown algae compared to other species. By heterologous
complementation and high-performance liquid chromatography analysis, desaturation activity of
recombinant UpPDS was confirmed by production of ζ-carotene in engineering E. coli co-transformed
with crtE, crtB and UpPDS. The L9(3 4) orthogonal test was used to optimize ζ-carotene fermentation
conditions of the engineering bacteria. The results showed that temperature had the most significant
effect on ζ-carotene production, the maximal yield of ζ-carotene could reach 5.0mg/L under the
optimal conditions. |
