Nitrate-sensitive ATPase activity and proton pumping in guard cell protoplasts of Commelina
- Abstract:
-
ATPase activity was measured in crude homogenates of guard cell protoplasts of Commelina communis L. using a linked enzyme assay. A low level of azide-sensitive ATPase activity was detected with a pH optimum of 6.8. This activity was stimulated by 0.01% (v/v) Triton X-100, and the pH optimum shifted to pH 7.4. Nitrate-sensitive ATPase activity was measured in the presence of azide and showed a pH optimum around pH 8.0. Proton pumping activity in a mixed population of vesicles from GC...

) if you have queries regarding unavailable content OR if you are aware of a full-text copy we can make available.
Content may be unavailable for the following four reasons
-
Version unsuitable
-
We have not obtained a suitable full-text for a given research output. See this page for more information.
-
Recently completed
-
Sometimes content is held in ORA but is unavailable for a fixed period of time to comply with the policies and wishes of rights holders.
-
Permissions
-
All content made available in ORA should comply with relevant rights, such as copyright. See this page for more information.

Clearance
-
Some thesis volumes scanned as part of the digitisation scheme funded by Dr Leonard Polonsky are currently unavailable due to sensitive material or uncleared third-party copyright content. We are attempting to contact authors whose theses are affected.
Alternative access to the full-text
You may be able to access the full-text directly from the publisher's website using the 'Publisher Copy' link in the 'Links & Downloads' box from a research output's ORA record page. This method may require an institutional or individual subscription to the journal/resource.
