PROCESS OF PREPARING GLUCAGON OR DERIVATIVES THEREOF IN A TRANSFORMED YEAST STRAIN

摘要

Glucagon or fragments or derivatives thereof are prepared by cultivation of a yeat strain transformed with a replicable expression vehicle comprising a gene encoding the expression of such products. Synthetic genes encoding glucagon or derivatives thereof have been constructed. Also provided are replicable expression vehicles comprising a replication system for providing stable maintenance in yeast and a DNA-sequence encoding glucagon or fragments or derivatives thereof and transformant yeast strains containing such expression vehicles.
