Chitin deacetylases are required for spore wall rigidity in Saccharomyces c
erevisiae. Two chitin deacetylase genes (CDA1 and CDA2) have been identifie
d in yeast. In this report we studied the biochemical properties of the chi
tin deacetylases encoded by CDA1 and CDA2 and we show how their elimination
directly affects the ascospore wall assembly. (C) 1999 Federation of Europ
