PsbH is an 8-kD phosphoprotein in the Photosystem II oxygen evolving core. The exact molecular function of PsbH has not been determined but it may play a role in mediating electron transfer between the secondary quinone acceptors, QA and QB.
The D1/D2 (PsbA/PsbD) reaction center heterodimer binds P680, the primary electron donor of PSII as well as several subsequent electron acceptors. D2 is needed for assembly of a stable PSII complex.
CP43 is a component of the proximal antenna of PSII and contains six transmembrane alpha helices and five hydrophilic loops that connect the membrane-spanning domains. CP43 is encoded by the psbC gene (ATCG00280).
CP47 is one of the components of the core complex of photosystem II (PSII). It binds chlorophyll and helps catalyze the primary light-induced photochemical processes of PSII. CP47 is encoded by ATCG00680.
NDHF is involved in the transfer of electrons from NAD(P)H: plastoquinone, via FMN and iron-sulfur centers, to quinones in the photosynthetic chain and possibly in a chloroplast respiratory chain.
The chloroplast NAD(P)H dehydrogenase (NDH) complex is involved in photosystem I (PSI) cyclic and chlororespiratory electron transport in higher plants. NDHD is a subunit of the NDH complex.
ATPI, ATP synthase F0 sector subunit a, F-ATPase subunit IV
Background:
ATPI is a subunit of ATPase complex CF0, which is a proton channel that supplies the proton motive force to drive ATP synthesis by CF1 portion of the complex.
