atpH

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.

UniProtKB entry for Miscanthus sinensis atpH

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 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.
