Gene Description

Plastid ATP synthase F0 c-ring subunit that forms part of the thylakoid proton channel coupling proton flow to ATP synthesis.

Core Functions

Forms part of the F0 c-ring rotor/proton channel of chloroplast ATP synthase, contributing to proton-translocating rotational ATP synthase activity.

Directly Involved In:
proton motive force-driven ATP synthesis
Cellular Locations:
chloroplast thylakoid membrane
In Complex:
proton-transporting two-sector ATPase complex, proton-transporting domain
Supporting Evidence:
  • file:MISSI/atpH/atpH-uniprot.txt
    F(1)F(0) ATP synthase produces ATP from ADP in the presence of a proton or sodium gradient.
  • file:MISSI/atpH/atpH-uniprot.txt
    Key component of the F(0) channel; it plays a direct role in translocation across the membrane.

  • UniProt describes AtpH as an F0 channel c-ring component of F(1)F(0) ATP synthase with a direct role in membrane translocation.

Suggested Questions for Experts

Q: Does Miscanthus atpH variation alter chloroplast ATP synthase proton conductance or photosynthetic ATP output?

Suggested Experiments

Experiment: Measure thylakoid proton motive force decay and ATP synthase conductivity in Miscanthus lines with altered atpH expression or sequence.

Type: targeted functional assay

Curation notes

  • QuickGO export is header-only; therefore no UniProt DR/InterPro/HAMAP-derived terms are listed as existing_annotations or proposed as NEW.
  • Core function focuses on the F0 proton-channel/c-ring role supported by UniProt's ATP synthase and F0 channel function statements.
