NON-OXIDATIVE ENZYMKS OF SPORK KXlRAfTS 113 



attack by the lytic enzyme is not, in fact, the first stage of the germination 

 process or that in intact spores the enzyme substrate is inaccessible or pres- 

 ent in some "protected" form. It may also follow that the function of the 

 germination stimulant may be to modify the substrate so as to make it sus- 

 ceptible to attack by the lytic system.
