basic FUNCTION	involved in the synthesis of CoQ by catalysing the prenylation of p-hydroxybenzoate with an all-trans polyprenyl group
	major function is to transport electrons from complexes I and II to complex III in the respiratory chain which resides in the mitochondrial inner membrane (Quinzii 2008)
