It is proposed that the C* domain located at the C-terminus of CesAand the TE domain located at the C-terminus of CesB works as a cooperative esterification and depsipeptide elongation center, repeatedly recruiting the action of the C* domain to oligomerize tetradepsipeptides to give octa- and dodecadepsipeptides prior to macrocyclization by the TE domain

The results if extrapolatable in case of -synuclein will imply that oligomers of -synuclein formed in the presence of zinc are also transient unstable entities not capable of inducing pores in lipid membranes
