Studi funzionali e strutturali sul wildtype e sul mutante γM23-K della ATP sintasi di Rhodobacter capsulatus: ruolo dell'ADP e della forza protonmotiva nell'attivazione dell'enzima e nell'accoppiamento dell'idrolisi di ATP alla traslocazione protonica

Autor: Rebecchi, Alberto <1978>

Nel presente lavoro di tesi sono state messe a confronto le ATP sintasi wild-type e γM23-K in cromatofori del batterio fotosintetico Rhodobacter capsulatus sotto gli aspetti funzionale e regolatorio. Si pensava inizialmente che la mutazione, in base

Met23Lys mutation in subunit gamma of F(O)F(1)-ATP synthase from Rhodobacter capsulatus impairs the activation of ATP hydrolysis by protonmotive force

Autor: Feniouk B. A., Anefors S., Mulkidjanian A. Y., Junge W., REBECCHI, ALBERTO, GIOVANNINI, DONATELLA, TURINA, MARIA PAOLA, MELANDRI, BRUNO ANDREA

H+-FOF1-ATP synthase couples proton flow through its membrane portion, FO, to the synthesis of ATP in its headpiece, F1. Upon reversal of the reaction the enzyme functions as a proton pumping ATPase. Even in the simplest bacterial enzyme the ATPase a

EFFECT OF THE gammaM23-K MUTATION ON ATP SYNTHASE ACTIVATION BY THE PROTONMOTIVE FORCE AND ON COUPLING ATP HYDROLYSIS TO PROTON TRANSLOCATION

Autor: REBECCHI, ALBERTO, TURINA, MARIA PAOLA, MELANDRI, BRUNO ANDREA, Feniouk B.

The single-site mutation M23-K in the gamma-subunit of the E.coli ATP synthase has been reported to perturb the energetic coupling between F1 and FO and to increase the transition state activation energy for ATP hydrolysis (1). We have introduced the

Structural and functional analysis of the reaction center-light harvesting complex of Rhodobacter sphaeroides

Autor: FRANCIA, FRANCESCO, DEZI, MANUELA, Busselez J., Levy D., REBECCHI, ALBERTO, Mallardi A., Palazzo G., MELANDRI, BRUNO ANDREA, VENTUROLI, GIOVANNI

Dimeric photosynthetic reaction center-light harvesting complex (RC-LH1) has been purified from the photosynthetic bacterium Rhodobacter sphaeroides grown under semiaerobic conditions. Removal of the detergent in the presence of lipids leads to the f
