Clay catalyzed polymerization of amino acid adenylates and its relationship to biochemical reactions

TL;DRAbstract

The adsorption and polymerization of alanine adenylate on montmorillonite at pH 7 when either its interspacial faces or its edger are blocked by an excess of histidine or sodium hexametaphosphate was investigated. Results indicate that alanine adenylate can be adsorbed any place on the interspacial spaces of the clay; however, adsorption of its phosphate part, which is limited to the edges of the clay, is necessary for polymerization to occur. As a result, polymerization takes place only at sites on the interspacial faces bordering the edges.
