Purification and characterization of a novel β-carotene-9′,10′-oxygenase from Saccharomyces cerevisiae ULI3

Objectives A novel β-carotene-9,10′-oxygenase (ScBCO2) has been characterized from Saccharomyces cerevisiae ULI3 to convert β-carotene to β-apo-10′-carotenal, which is a precursor of the plant hormone strigolactone.
