Talk:Chemotaxis

message: Although user Kohlasz may be an expert in the area, I find at least one instance of a contribution that violates WP:NOR. Also, a figure under the subheading In the mirror of publications uploaded by user Kohalasz is misleading in the sense that it has not been published in a peer reviewed journal, although, the reader is lead to believe it has. —―

message: Has anyone noticed that the picture showing CCW and CW rotation of the E. Coli are actually two pictures of CW (Clockwise) rotation? Just that the arrows are at different positions but the direction is the same.    —Preceding unsigned comment added by 201.20.120.114 (talk) 20:11, 19 September 2007 (UTC)

message: I have taken the liberty of cleaning up the English grammar and spelling. Somebody with more knowledge of the subject should review the changes to make sure the content is still correct, since I know very little about this subject, and I had to take a guess at the original meaning in a couple of places.
In addition, the following sentence is still hard to parse in English, and I didn't want to guess as to the meaning:
Chemoattractant moiety of fMLF elicited in neutrophil granulocytes and monocytes.

thread_title:  Grammar and spelling corrections 

message: There is a misconception in the paragraph dedicated to E. Coli chemotaxis, it states:
"However, the methylation system alone cannot account for the wide range of sensitivity that bacteria have to chemical gradients."
That is not correct, the integral feedback created by the methylation pathway is the only responsible for wide range sensitivity, as it allows the system to maintain its high sensitivity operating point over a wide range of backgrounds. more about this can be found in [1]. The article further states:
"Additional regulatory mechanisms such as receptor clustering and receptor-receptor interactions also modulate the signalling pathway."
It is known today that receptor interactions and clustering do not modulate the signaling pathway. It is true however that the total value of the high sensitivity (not the range on which it is maintained) is enhanced by mechanisms such as receptor-receptor interactions, receptors clustering, and the ultrasensitive response of the flagellar motor to the CheY-P signal [2,3].
Because of this I will slightly edit those lines.

message: Hi, all
Could we include a snippet on the etymology of "chemotaxis"? Chemo - chemical, taxis - purposefully directed organization (greek).
Best,

message: According to its first sentence, Biased random walk (biochemistry) is about chemotaxis, so it makes sense to merge it with this article. There is not even an article about Biased random walks in general yet. RockMagnetist (talk) 23:16, 9 February 2013 (UTC)

I have just added archive links to  on Chemotaxis. Please take a moment to review my edit. If necessary, add  after the link to keep me from modifying it. Alternatively, you can add  to keep me off the page altogether. I made the following changes:
*Replaced archive link archive.org/web/20080427114159/http://research.microsoft.com/displayArticle.aspx?id=1572 with https://web.archive.org/20121022100707/http://research.microsoft.com/displayArticle.aspx?id=1572 on http://research.microsoft.com/displayArticle.aspx?id=1572

thread_title:  External links modified 

message: A(nother) poorly structured article with section after section of unsourced material, and sophistication and rigour of draft student work. Placing an expert needed tag. A summary of any one good review article would be sufficient to redirect this from the non-authoritative editorial hodgepodge that it is becoming, to a reliably structured outline with the vast majority of material needed (to dispense with most of the accumulated nonsense). Sorry to be blunt, but there it is. (A day off, and eight hours later, and unable to create a coherent web of information around one topic, because each article consulted is another mares nest of more-time-required-than-value-returned.)

replies: text: Le Prof, you have some valid concerns, but I think you have gone overboard with your tags. If several sections have problems with sources, it's best to just tag the whole article. Also, the expert tag is rather verbose - why not just say it on the talk page? RockMagnetist(talk) 04:46, 4 April 2017 (UTC)
