MetaCyc Enzyme: dolichol kinase

Gene: SEC59 Accession Number: G-5521 (MetaCyc)

Synonyms: dolichol phosphokinase

Species: Saccharomyces cerevisiae

Summary:
The product of gene SEC59 was computationally predicted to be highly hydrophobic and to contain two potential N-glycosylation sites [Bernstein89]. The product of gene SEC59 contains a 13-amino acid consensus sequence thought to be involved in dolichol recognition. This sequence is also found in the glycosyltransferase products of genes ALG1, ALG7, and DPM1 [Albright89].

Human dolichol kinase has been cloned and expressed in Escherichia coli and its topological arrangement as a membrane protein characterized [Shridas06]. In humans, mutations in the gene encoding dolichol kinase can cause a lethal metabolic disorder [Kranz07].

Enzymatic reaction of: dolichol kinase

EC Number: 2.7.1.108

a dolichol + CTP <=> a dolichyl phosphate + CDP + H+

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.

The reaction is favored in the direction shown.

In Pathways: dolichol and dolichyl phosphate biosynthesis

Summary:
Saccharomyces cerevisiae cells carrying the SEC59 mutation are deficient in dolichol kinase activity [Heller92].
