Article Grading: The following comments were left by the quality and importance raters: (edit · refresh) Rated "high" as high school/SAT biology content. The article would benefit from figures and expansion beyond transmembrane ATPases (e.g. adding other families such as AAA+ ATPases etc.) - tameeria 23:02, 18 February 2007 (UTC)

[edit] Error?

Is this an error?

for example, 3 Na+ ions inward and 2 K+ ions outward per ATP hydrolyzed, for the Na+/K+ exchanger.

seeNaKATPase Function section

You are absolutely right, I changed this. -postglock 14:25, 6 April 2006 (UTC)

[edit] ATPase vs ATP Synthase

Also, does anyone know if ATPase is strictly an enzyme that dephosphorylises (is that a word?) ATP? My bio lecturer uses that same word for ATP synthase in mitochondria. Similarly, does anyone know if the -ase suffix suggests enzymes that that break down the root of the name? I suspect not, ala, RNA polymerase.... -postglock 14:25, 6 April 2006 (UTC)

Yes dephosphorylises is a word, second no. F- ATPases work like V-ATPases but in reverse allowing H+ to flow with the gradient and makes ATP with the energy dived. The worked of the Cell by Becker, Kleinsmith and Hardin has a good chapter on ATPases. I’ll up date this article from the information with in it soon if there are no objections. -jasoninkid 16 April 2006

Thanks for the response, and certainly update the article with the information, any positive additions are appreciated! I'm still don't understand this completely though, I mean, if ATP synthase works in reverse, and also has the capability to work like an ATPase, then could it be (structurally) called an ATPase? -postglock 01:14, 17 April 2006 (UTC)
