Cell-free bioproduction of b-cryptoxanthin and zeaxanthin

Abstract

A cell-free system is provided to produce β-cryptoxanthin and zeaxanthin from β-carotene. β-carotene is added to a reaction mixture comprising a β-carotene hydroxylase enzyme (CrtZ). The reaction mixture may be aqueous and may comprise a co-solvent, e.g., an organic co-solvent, such as THF.
