text: As shown in Table 2, the specific activity of native CysE was 67.5 ± 5.6 mU/mg protein, and maintained only 5.4 ± 0.7% residual activity to 3.6 ± 0.4 mU/mg protein when 100 μmol l-cysteine was added, suggesting that the CysE from C. glutamicum was also strongly feedback-inhibited by l-cysteine, which greatly limited the biosynthesis of l-cysteine.
