Abstract: | The cytosol of the sporangiophore of has considerable chitinolytic activity. This activity is strongly dependent on the presence of a dialyzable activator. Maximal activity is achieved at pH 5.5; and ionic strength and Ca++ or Mg++ have little effect. Ungerminated spores do not contribute activity. The possibility is discussed that chitinase might be involved in the growth response system by transiently loosening the rigid framework of chitin at specific and defined points. |
