A survey is given of the lycopene cyclase genes present in bacteria, fungi and plants where two completely unrelated types exist. One is the classical monomeric bacterial β-cyclase gene, crt Y which may be an ancestor of crtL the gene for a β-cyclase in cyanobacteria. From crtL a line of evolution can be drawn to plant β- and ε-cyclase genes and to the gene of capsanthin/capsorubin synthase. In Gram-positive bacteria two genes crtYc and crtYd are present. They encode two proteins which have to interact as a heterodimer for lycopene β-cyclization. From this type of lycopene cyclase gene the fungal lycopene cyclase/phytoene synthase fusion gene evolved.
