Two weeks ago our Wikipedia article on Circular permutation in proteins was featured in on Wikipedia’s mainpage as a “Did you know…” article:

Did you know... that the protein Concanavalin A (pictured) cuts itself in two and then reassembles in a circularly permuted order?

We were quickly replaced by the Rice stink bug, but a snapshot of the page Wednesday morning is available from WebCitation.

Submitting an article for DYK is a bit of a hassle: think up a good hook, make sure your article is up to snuff, find someone else to review your hook favorably… However, the results of getting on the main page are stunning. Here’s the number of page views for Circular permutation in proteins this month:

daily page views
Daily page views for Circular permutation in proteins in April 2012. The page was featured on DYK on the labelled day.

Prior to our update, the page was seeing under 20 views per day. Since then, we’ve mostly been getting 20-60 views a day, with a few spikes probably due to attention from blogs. But being featured on the main page for just 9 hours resulted in 1440 hits.

Topic Pages were also featured in Daniel Mietchen’s new post to the PLoS blog, Bridging the Journal-Wikipedia Gap.

Update: In the interest of full disclosure, the hook was badly phrased. Concanavalin does not really cut “itself” in two, as the full procedure requires a restriction enzyme to make the cuts. This is a flaw with the DYK hook rather than the article itself, which merely describes the procedure as an “unusual protein ligation.”
