Some classes of mutants were obtained from the parental strain as the source of genetic material for transduction:

I) A strain that are resistance to thialysine

II) A strain in which both the threonine-regulated AK and HD were resistant to feedback inhibition by threonine

III) A strain is selected for ß-hydroxynorvaline Sensitive, in which HDI was sensitive to both inhibition and repression and the threonine-regulated AK was constitutively synthesized
