Structure, function and biosynthesis of carotenoids in the moderately halophilic bacterium Halobacillus halophilus.

Abstract excerpt

Inhibitor studies and mutant analysis revealed a C(30) pathway via 4,4'-diapophytoene and 4,4'-diaponeurosporene to 4,4'-diaponeursoporene-4-oic acid esters related to staphyloxanthin in Halobacillus halophilus. Six genes may be involved in this biosynthetic pathway and could be found in two adjacent gene clusters. Two genes of this pathway could be functionally assigned by functional pathway complementation as a...
