Product Speculation from Carotenogenic Gene Cluster of Genome, and Identification of Myxol and Functional Analysis of Each Gene.

Myxol, a monocyclic carotenoid with β- and ψ-end groups, has been identified in only a limited number of bacteria, such as flavobacteria and cyanobacteria. Despite its biological significance, the biosynthetic pathway of myxol is not well understood, and studies on its physiological functions and biological activities are limited because of its rarity. BLAST homology searches for carotenoid biosynthesis genes in the genome of were performed.
