In other studies, after incubation of labeled captan with 
Neurospora crassa conidia, most of 35§ was found to be bound to water- 
soluble and protein fractions. 35§ occurred largely in oxidized 
glutathione and in a compound believed to be a thiazolidine derivative 
of glutathione. The same product was obtained by reacting glutathione 
with carbonyl sulfide, a known decomposition product in the reaction 
of captan with thiols (1208, 1689).
