[Dicyclohexylcarbodiimide as an inhibitor of light- and pyrophosphate-induced formation of membrane potential in chromatophores of purple bacteria].


N,N'-Dicyclohexylcarbodiimide (DCCD) suppresses the uptake of penetrating tetraphenylborate anions by Rhodospirillum rubrum chromatophores during cyclic and non-cyclic electron transfer and ATP and PP i hydrolyses. The photochemical activity of the bacteriochlorophyll reaction centers of the chromatophores in insensitive to DCCD. This supports the view that… (More)
