ACTION OF ARGINASE

TABLE II 



The data indicate a maximum velocity of reaction at or near 

 50°C. At 70° the enzyme is practically inactive. If the data be 

 plotted on coordinate axes the graph is practically a straight line 

 between 10° and 50°. 



The conditions of the experiment were not such as to permit 

 one to calculate the temperature coefficient of the enzyme reaction. 

 This defect will be remedied in future work. 



The influence of other factors (such as substrate and enzyme 

 concentration) upon the kinetics of the reaction is now under investi- 

 gation.
