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.
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.
In chloroplasts, transcription of plastid genes is mediated by two types of RNA polymerase: plastid-encoded RNA polymerase (PEP) and nuclear encoded RNA polymerase (NEP). PEP is composed of four core subunits (α, β,β’,β’’) and a promoter recognition subunit (σ factor). RpoC2 (ATCG00170) is the β’’ subunit of PEP.
Cytochrome b6-f complex subunit 4 is component of the cytochrome b6-f complex, which mediates electron transfer between photosystem II (PSII) and photosystem I (PSI), cyclic electron flow around PSI, and state transitions.
