Abstract
The mechanism of action of the systemic fungicide carboxin was studied. The nonheme Fe-sulfurprotein (FeSPP) of the succinodehydrogenase, which is located on the main route of the cytochrome mediated respiration, is apparently the alternative terminal oxidase itself. This property seems to be based on the ability for autoxidation in some organisms [Rhodotarula mucilagihosa and Procendida albicans were used] where the Fe-atoms are oxygenized and reach the maximal coordination number of 6. Carboxin, which also attacks the normal electron flow at the FeSPP of the succinodehydrogenase, is probably able to inhibit simultaneously under certain circumstances the cyanide-insensitive respiration organisms sensitive to carboxin.This publication has 3 references indexed in Scilit:
