The enzyme, isolated from the archaeon Haloarcula japonica, is involved in the biosynthesis of the C50 carotenoid bacterioruberin. In this pathway it catalyses the introduction of hydroxyl groups to C3′′ and C3′′′ of bisanhydrobacterioruberin to generate bacterioruberin.
The expected taxonomic range for this enzyme is: Haloarcula japonica
The enzyme, isolated from the archaeon Haloarcula japonica, is involved in the biosynthesis of the C50 carotenoid bacterioruberin. In this pathway it catalyses the introduction of hydroxyl groups to C3'' and C3''' of bisanhydrobacterioruberin to generate bacterioruberin.
the gene cluster, including genes c0507, c0506, and c0505, is involved in the synthesis of bacterioruberin. Genes c0507, c0506, and c0505 encode a carotenoid 3,4-desaturase (CrtD), a bifunctional lycopene elongase and 1,2-hydratase (LyeJ), and a C50 carotenoid 2'',3''-hydratase (CruF), respectively. The three carotenoid biosynthetic enzymes catalyze the reactions that convert lycopene to bacterioruberin in Haloarcula japonica. Biosynthetic pathway of C50 carotenoids, overview

construction of an enzyme deletion DELTAc0505 mutant strain, the mutant is constructed by homologous recombination. The transcriptions of genes c0507 and c0506 in the DELTAc0505 strain are confirmed by RT-PCR, and the disruption of c0505 does not affect the expression of the upstream genes in the same cluster. In vivo complementation using intact c0505 gene introduced into transformant DELTAc0505(pJc0505), the carotenoid composition of the DELTAc0505(pJc0505) transformant is restored and similar to that of the wild-type
