Catalytic triad

Voting period is over. Please don't add any new votes. Voting period ends on 8 Jan 2016 at 21:45:05 (UTC)

Original – An enzyme (TEV protease) bound to a substrate (black) contains a catalytic triad of residues (red). The triad consists of an acidic residue (Acid), histidine (Base) and the nucleophile (Nuc). In the case on TEV protease, the acid is aspartate and the nucleophile is cysteine. (PDB: 1lvm)

Reason: This is a professional-quality scientific illustration of a protein, highlighting the key structural features underlying a very common catalytic mechanism for enzymes. The chemistry of the catalytic triad is commonly taught in undergraduate biochemistry courses, giving a high-quality illustration high encyclopedic value. (This nomination is a follow-up to the conversation in this recent delisting nomination for a dated- and generic-looking protein illustration. This newly nominated image would give us a high-quality protein example in a modern style.) Opabinia regalis (talk) 21:45, 26 December 2015 (UTC)[reply]

Comment: I confess that I don't really know much about this sort of thing, but this image is below the size requirements and looks to have been slightly up-sized (visible pixelation on diagonal lines) anyway. In addition, would an svg not be preferred? Josh Milburn (talk) 02:22, 27 December 2015 (UTC)[reply]
Oppose – On size, per Josh. I must confess I know zilch about this sort of thing, and thus tend to think it abstruse for most readers, but realize I'm biased in this view. Sca (talk) 15:14, 27 December 2015 (UTC)[reply]
Comment Great illustration, I have to agree on the size issues, though. Perhaps go to WP:Graphics lab and ask for it to be made SVG? Adam Cuerden ^(talk) 21:04, 27 December 2015 (UTC)[reply]
- I imagine Evolution and evolvability could upload a larger SVG version, time permitting, but only the annotation elements (lines and text) would be scalable; the protein images are raytraced. Opabinia regalis (talk) 23:39, 28 December 2015 (UTC)[reply]
Comment as creator - Thank you for the recommendations. I can update to 2800x1600px pretty easily (adding lines and text to larger size version). I'm also happy make an svg instead if there's consensus that that's better, however I've tended to favour raster when vector benefits only a few elements, since I think the average user finds pngs easier to download and use. As Opabinia regalis suspected, the protein image itself would just be an embedded raster within the vector file. T.Shafee(Evo﹠Evo)^talk 02:52, 30 December 2015 (UTC)[reply]

Done - I've uploaded 2800px wide png version! T.Shafee(Evo﹠Evo)^talk 11:32, 5 January 2016 (UTC)[reply]
