Function
UPPS_YEAST With SRT1 or RER2, forms the dehydrodolichyl diphosphate synthase (DDS) complex, an essential component of the dolichol monophosphate (Dol-P) biosynthetic machinery. Adds multiple copies of isopentenyl pyrophosphate (IPP) to farnesyl pyrophosphate (FPP) to produce dehydrodolichyl diphosphate (Dedol-PP), a precursor of dolichol which is utilized as a sugar carrier in protein glycosylation in the endoplasmic reticulum (ER).[1]
Publication Abstract from PubMed
The polyprenoid glycan carriers are produced by cis-prenyltransferases (cis-PTs), which function as heterodimers in metazoa and fungi or homodimers in bacteria, but both are found in plants, protista and archaea. Heterodimeric cis-PTs comprise catalytic and non-catalytic subunits while homodimeric enzymes contain two catalytic subunits. The non-catalytic subunits of cis-PT shows low sequence similarity to known cis-PTs and their structure information is of great interests. Here we report the crystal structure of Nus1, the non-catalytic subunit of cis-PT from Saccharomyces cerevisiae. We also investigate the heterodimer formation and active site conformation by constructing a homology model of Nus1 and its catalytic subunit. Nus1 does not contain an active site, but its C-terminus may participate in catalysis by interacting with the substrates bound to the catalytic subunit. These results provide important basis for further investigation of heterodimeric cis-PTs.
