Table 2 Kinetic parameters of AbnZ2 and AbnZ3

From: Characterization of abnZ2 (yxiA1) and abnZ3 (yxiA3) in Paenibacillus polymyxa, encoding two novel endo-1,5-α-l-arabinanases

Enzyme V(U/mg) Vmax(U/mg) kcat(s−1) K m (mg/ml) kcat/K m
AbnZ2 18.8 ± 2.3 60.6 ± 5.6 81.8 ± 7.6 15.4 ± 3.1 5.3
AbnZ3 17.5 ± 3.0 51.8 ± 6.7 44.8 ± 5.8 19.3 ± 2.6 2.3
  1. Specific activity was measured by purified recombinant arabinanase with linear arabinan at 30°C, pH 6.0. The data shown are the averages standard deviations of three independent experiments.
