Figure 5: (a) PLA2 activity of Bothrops roedingeri venom and peak 4 (BrTX-I); (b) effect of substrate concentration on the kinetics of BrTX-I (PLA2) activity. (c) effect of temperature on the PLA2 activity of BrTX-I; (d) effect of pH on BrTX-I activity; (e) influence of ions (10 mM each) on PLA2 activity in the absence or presence of 1 mM Ca2+. The results of all experiments are the mean SE, of three determinations ( ) and (f) amino acid composition of BrTX-I from Bothrops roendingeri snake venom.
