A carotenoid biosynthesis gene cluster involved in canthaxanthin production was isolated from the photosynthetic Bradyrhizobium sp. strain ORS278. This cluster includes five genes identified as crtE, crtY, crtI, crtB, and crtW that are organized in at least two operons. The functional assignment of each open reading frame was confirmed by complementation studies.
从光合慢生根瘤菌属菌株ORS278中分离出一个参与虾青素合成的类胡萝卜素生物合成基因簇。该基因簇包括五个被鉴定为crtE、crtY、crtI、crtB和crtW的基因,它们至少以两个操纵子的形式组织。每个开放阅读框的功能分配通过互补研究得到证实。
