PROCESS FOR PRODUCING ASPARTAME |
摘要 |
The artificial sweetener aspartame, a dipeptide with the formula Asp-Phe-me, is produced using a cloned micrcorganism. A DNA which codes for a large stable peptide comprised of the repeating amino acid sequence (Asp-Phe)n is inserted into a cloning vehicle which in turn is introduced into a suitable host microorganism. The host microorganism is cultured and the large peptide containing the repeating Asp-Phe sequence is harvested therefrom. The free carboxyl group of the large peptide is benzylated and then hydrolysed to benzyl Asp-Phe dipeptides. This dipeptide is methylated and then debenzylated to form aspartame. |
