Abstract excerpt

l-asparaginases (EC 3.5.1.1) play an important role in nitrogen mobilization in plants. Here, we investigated the biochemical and biophysical properties of potassium-dependent (PvAspG1) and potassium-independent (PvAspG-T2) l-asparaginases from Phaseolus vulgaris. Our previous studies revealed that PvAspG1 requires potassium for catalytic activation and its crystal structure suggested that Ser-118 in the...
