Dolichol kinase

In enzymology, a dolichol kinase () is an enzyme that catalyzes the chemical reaction
:CTP + dolichol \rightleftharpoons CDP + dolichyl phosphate
Thus, the two substrates of this enzyme are CTP and dolichol, whereas its two products are CDP and dolichyl phosphate.
This enzyme belongs to the family of transferases, to be specific, those transferring phosphorus-containing groups (phosphotransferases) with an alcohol group as acceptor. The systematic name of this enzyme class is CTP:dolichol O-phosphotransferase. This enzyme is also called dolichol phosphokinase. This enzyme participates in N-glycan biosynthesis.
In humans dolichol kinase is encoded by the ''DOLK'' gene.〔(【引用サイトリンク】 url = http://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=22845 )
== Function ==

Dolichyl monophosphate is an essential glycosyl carrier lipid for C- and O-mannosylation and N-glycosylation of proteins and for biosynthesis of glycosylphosphatidylinositol anchors in endoplasmic reticulum (ER). Dolichol kinase catalyzes CTP-mediated phosphorylation of dolichol, the terminal step in de novo dolichyl monophosphate biosynthesis.
