Self-association of a phosphate receptor along and with a lipidomimetic in water: Effect of receptor low concentrations on the catalytic activity of mixed systems

► Receptor can self-associate in the concentration range 10−13-10−5 M. ► Formed associates are of a different nature before and after 10−7 M. ► Mixed micelles of receptor and lipidomimetic at 10−13-10−5 M of receptor was studied. ► Dependence of the catalytic activity of systems correlates with the size of micelles. ► Maximum effect of receptor at 10−9 M on catalytic activity of mixed systems was found.
