2.7.2.4 | A279T |
isolated from Corynebacterium glutamicum strain IWJ001, aspartate kinase mutant AKA279T is encoded by gene lysC1. The mutant enzymes is completely resistant to feed-back inhibition by L-threonine and L-lysine |
-, 738802 |
2.7.2.4 | A380I |
the mutant has 11.32fold higher enzyme activity than the wild type enzyme, enhanced thermal stability and shows weakened inhibition with L-lysine |

2.7.2.4 | C428R |
mutation is not directly involved in L-lysine binding. Mutation located within regulatory domain, participates in the allosteric regulation within regulatory domain. Mutation greatly reduces L-lysine inhibition |
