Effects of disalicylidenepropanediamines on photosynthetic electron transport of isolated spinach chloroplasts.

Abstract

The effects of disalicylidenepropanediamine (DSPD) and disulfo-disalicylidenepropanediamine (sulfo-DSPD) on the photosynthetic electron transport of isolated chloroplasts have been reexamined.Our data suggest that DSPD, but not sulfo-DSPD, is an effective inhibitor of electron transport between photosystem II and photosystem I before or at plastocyanin. Furthermore, both DSPD and sulfo-DSPD block electron transport at the site of ferredoxin.Under certain conditions DSPD and even more so sulfo-DSPD function as autooxidizable electron acceptors.Finally it is shown that DSPD can cause an inhibition of photophosphorylation.According to our results the use of DSPD as a specific inhibitor of ferredoxin-dependent reactions has to be questioned.
