| Type: | Conserved_site | Name: | Phytoene dehydrogenase, bacterial-type, conserved site |
| Description: | Phytoene dehydrogenase (phytoene desaturase) is an enzyme of carotenoid biosynthesis that converts phytoene into zeta-carotene via the symmetricalintroduction of two double bonds at the C-11 and C-11' positions of phytoene. The sequence of phytoene dehydrogenase from bacteria (gene crtI or carC) andfungi (gene AL-1) are not related to that from cyanobacteria and plants but are evolutionary related [] to that of another enzyme of carotenoid biosynthesis,methoxyneurosporene dehydrogenase (gene crtD). There are two glycine-rich conserved regions, both of which probably play arole in the binding of either FAD or NAD. The first conserved region is in the N-terminal section while the second one is in the C-terminal section. | Short Name: | Phytoene_DH_bac_CS |
