Chitin synthetase was solubilized with digitonin from a particulate yeast
fraction. The solubilized enzyme, which did not sediment at 200,000 X g and
emerged after the void volume in a Sepharose 6B column, was active only
after treatment with a protease. This confirms that chitin synthetase
exists in the plasma membrane as a zymogen and that initiation of the
chitin septum occurs by localized activation of the enzyme. By differential
extraction with sodium cholate and digitonin, followed by chromatography on
Sepharose 6B, a 20-fold purification of the enzyme was achieved with
respect to the crude particles. The purified enzyme showed a requirement
for a phospholipid; phosphatidylserine and lysophosphatidylserine were the
best activators. Unsaturated fatty acids strongly inhibited synthetase
activity, whereas their saturated counterparts were inert. The solubilized
enzyme catalyzed the formation of insoluble chitin in the absence of added
primer. The synthetic polysaccharide was examined by electron microscopy
and found to consist of lozenge-shaped particles about 60 nm long and 10 nm
wide.
