Abstract
Mutants of E. coli having alternative requirements for isoleucine or one or more threonine isomers were studied. It was concluded that in some cases the growth factor was required to overcome an internal inhibition brought about by the overproduction of a certain metabolite. A unified scheme relating the biosynthesis of isoleucine, valine and threonine could not be devised on the basis of the growth requirements alone.Keywords
