Talk:EnvZ/OmpR two-component system

Membrane surface tension

"The sensory domain detects the changes caused in membrane surface tension due to changes in medium osmolarity."

This sentence appears to be cited from source 3's background section. However, the article only states the possibility: "The primary signal for such a conformational change may be that caused by a change in the physical membrane-tension due to osmotic pressure," and cites an article which does not make this same claim.

I think that sentence was just speculation on the part of the author, unless someone else can find a different paper where EnvZ was more closely studied.

Good point - in fact there seems to be more recent data suggesting that's not the case. I've updated the text. Opabinia regalis (talk) 21:03, 14 April 2017 (UTC)[reply]

Picture for the membrane part

I think a picture would be nice to shows how this osmo-regulation works at the membrane. We have one image showing the transcription situation, but nothing to show how EnvZ relates to the membrane and where the other proteins are. I initially thought that OmpF and OmpC have to two with the sensing part, not understanding that these are just the porines that are synthesized. 2A02:8388:1641:5500:8207:8CE:DF2:AB90 (talk) 17:41, 5 December 2022 (UTC)[reply]

Here is one picture that could be used for inspiration in the article https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7192543/ from 2020; not sure if we can re-use that image, but it should not be too difficult to make a sketch, if anyone has some drawing skills. 2A02:8388:1641:5500:8207:8CE:DF2:AB90 (talk) 17:43, 5 December 2022 (UTC)[reply]
