title: The enhancement activities 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.
