CTP + dolichol
CDP + dolichyl phosphate
-
DK1 is responsible for the final step of the de novo biosynthesis of dolichol phosphate, defect in human DK1 affects the biosynthesis of dolichol phosphate by the disturbance of the final phosphorylation step, causes lethal phenotype with death in early infancy.
dolichyl phosphate is involved in several glycosylation reactions, such as N-glycosylation, glycosylphosphatidylinositol (GPI)-anchor biosynthesis, and C- and O-mannosylation

-
-
CTP or other phosphate group donors like ATP, GTP or UTP are not required for maximal activity

?
additional information
?
-
-
the chain length of eukaryotic dolichol molecules is species specific and differs from 14-17 isoprene units in unicellular organisms like the yeasts Saccharomyces cerevisiae and Schizosaccharomyces pombe, mammalian cells produce longer dolichol molecules with 18-21 isoprene units

-
microsomal enzyme shows a marked preference for saturation of the alpha-isoprene, dolichol-16 and dolichol-19 are 2.5fold more active than the corresponding polyprenols, the enzyme is twice as active against naturally occurring polyprenol-16 (alpha-cis-isoprene) compared to synthetic alpha-trans-polyprenol-16, all-trans-2,3-dihydrosolanesol and solanesol are not substrates
