Engineering CrtW and CrtZ for improving biosynthesis of astaxanthin in Escherichia coli
{{output}}
This study engineered β-carotene ketolase CrtW and β-carotene hydroxylase CrtZ to improve biosynthesis of astaxanthin in Escherichia coli. Firstly, crtW was randomly mutated to increase CrtW activities on conversion from β-carotene to astaxanthin. A crtW* m... ...
