Zeaxanthin and menaquinone-7 biosynthesis in Sphingobacterium multivorum via the methylerythritol phosphate pathway.
Feeding of [1-(13)C]glucose, [U-(13)C(6)]glucose, [3-(13)C]alanine and [1-(13)C]acetate to Sphingobacterium multivorum showed that this bacterium utilizes the methylerythritol phosphate pathway for the biosynthesis of menaquinone-7 and zeaxanthin, a carotenoid of industrial importance. Differential incorporation of the labeled precursors gave some insight into the preferred carbon sources involved in isoprenoid biosynthesis.
