[Intracellular pool of free amino acids in a wild strain of Corynebacterium glutamicum and its lysine-producing mutants].

Abstract excerpt

The intracellular content of free amino acids was measured in the wild-type strain of Corynebacterium glutamicum 13032 and its lysine producing mutants 410 and 133, resistant to the combined effect of threonine and S-2-aminoethyl cysteine, a lysine analog. After 18- and 48-hour cultivation of all strains the major components of the amino acid pool were glutamic acid, alanine and lysine, and those of the cell-free...
