Conserved Site

Phytoene dehydrogenase, bacterial-type, conserved site (IPR008150)

Short name: Phytoene_DH_bac_CS


Phytoene dehydrogenase (phytoene desaturase) is an enzyme of carotenoid biosynthesis that converts phytoene into zeta-carotene via the symmetrical introduction 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) and fungi (gene AL-1) are not related to that from cyanobacteria and plants but are evolutionary related [PMID: 2144293] to that of another enzyme of carotenoid biosynthesis, methoxyneurosporene dehydrogenase (gene crtD). There are two glycine-rich conserved regions, both of which probably play a role 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.
