on the basis of Escherichia coli undecaprenyl diphosphate synthase crystallographic structure the yeast Rer2p model is constructed. In the model three amino acid residues inserted into the sequence corresponding to the floor region of the tunnel extends the bottom loop what results in the required increase of the tunnel volume. Thermal fluctuations of this loop occasionally create a hole in the tunnel floor, making escape of polyprenol omega end out of the tunnel possible what switches off the control mechanism of product length thereby allowing a practically unlimited elongation process leading to an exponential distribution of longer chain polyprenols
