Abstract

A genetic sequence coding for the production of a protein having the activity of homoserine dehydrogenase and having two Pst I cleavage sites in its DNA chain and a molecular weight of 2.24 Md, is incorporated into a vehicle capable of replication in Coryneform bacteria and used to produce L-threonine and L-isoleucine by fermentation.
