Nonenzymatic Catalysis by bivalent ions of Be, Mg, Ca, Zn, Mn, Ni and Co and bioorganic phosphates of the formation of hydroxamic acids from acetate or amino acids has been studied systematically.Increased yields of hydroxamate were observed at particular combinations of reactants.The most prominent increase (ca. 15-fold) was found with acetate and Ni++, and with a combination of ATP and Be++.Among others especially ribose-5-phosphate and glucose-5-phosphate enhanced yields in the presence of most metal ions.Since no release of inorganic phosphate was observed, this effect cannot be interpreted as an evidence for intermediate transphosphorylation reactions; it may also result from simple catalytic effects of metal sugar complexes. - Keywords: Prebiological Evolution, Bioids, Transphosphorylation, Hydroxylamine, Acylate Activation
