## Abstract Waterβinsoluble oligomers were synthesized from Lβmethionine ethyl ester with papain as the catalyst. LβOligomethionine was obtained in yields of 50% when synthesis was carried out in highly concentrated citrate buffer at pH 5.5. Yields of up to 85% were obtained when the enzymatic synt
Free Staphylococcus auseus V8 proteinase was applied to coupling reactions of Z-Glu-OMe, Z-Glu-OBzl, Z-Ala-Glu-OMe and Z-Ala-Ala-Glu-OMe with various amino acid amides and peptides in acetonitrile containing 5 vol. % of water. No synthesis of Z-Asp-Leu-NH, was achieved under the same conditions. The
