The enhancement activites of histidyl-histidine in some prebiotic reactions

Abstract
The prebiotic synthesis of His and its dimer has led us to study the possible catalytic properties of His-His. The enhancing effect of His-His has been tested in the dephosphorylation of dAMP, the hydrolysis of oligo(A)12, and the oligomerization of 2′,3′-cAMP.
