Abstract

The function of gene sll0033 from Synechocystis 6803 which is homologous to the bacterial crtI-type phytoene desaturase genes was elucidated as a novel carotene isomerase. Escherichia coli transformed with all genes necessary for the formation of ζ-carotene and expressing a ζ-carotene desaturase synthesized the positional isomer prolycopene (7,9,7′,9′Z lycopene) which cannot be cyclized in the subsequent reactions to a- and β-carotene. Upon cotransformation with sll0033, the formation of all-E lycopene is mediated instead.
