The still opened questions about polyisoprenoids synthesis and function in plants
Polyisoprenoids (polyprenols and dolichols) are a widespread group of chemical compounds found in living organisms, obtained through the polymerization of isoprene residues. Up to date the best-studied function of polyisoprenoids is their role as saccharide carriers in protein posttranslational modification such as glycosylation. However, taking into account their large length diversity and high accumulation in organisms, most likely not the only one. We try to determine the role of polyisoprenoids in response to environmental stresses, especially in heat stress. Enzymes called cis-prenyltransferases (CPTs) are responsible for elongating the isoprene chain in cells. In plants CPTs are able to synthesize products from 6 to 130 isoprene units, accumulated as a families with one dominant element. The still opened question is, whether the subcellular localization of CPTs affected on the synthesized product chain length?
