The astaxanthin biosynthesis gene cluster in Paracoccus haeundaensis consists of six genes: crtW, crtZ, crtY, crtI, crtB, and crtE contain 726, 486, 1158, 1503, 912, and 879 base pairs, respectively. Individual carotenoid biosynthesis genes of P. haeundaensis have now been expressed in E. coli and each gene product has been purified to homogeneity. Their molecular characteristics, including enzymatic activities, are reported here.
