BIOPRODUCTION OF ASTAXANTHIN USING MUTANT CAROTENOID KETOLASE AND CARTONENOID HYDROXYLASE GENES

摘要

Protein engineered nucleic acid fragments encoding a CrtO ketolase and a CrtZ hydroxylase are provided with increased astaxanthin synthesis activity. Methods using the present nucleic acid fragments are also provided for increasing or altering astaxanthin production in suitable production hosts.
