suggest removing "Too-technical" tag[edit]

This article has a boilerplate {{Technical}} tag at the beginning, but I think it should be removed. In its present form the article's introduction adequately explains what pyrrolysine is--an unusual amino acid occurring in only a few organisms. Given that pyrrolysine is a fairly obscure biochemical, which so far has not been touted as a nutritional supplement, the article is less likely to be viewed by generalist readers than say, tryptophan or amino acid, or taurine and accordingly the use of a few technical terms like methanogenic archaea in the introduction is not inappropriate.CharlesHBennett (talk) 16:34, 29 November 2011 (UTC)

I think a strong effort to establish a context for understanding to the non-technical readership would be appropriate. Given that there are several redlinks, this article is presently inaccessible to the general readership. I'd suggest the tag remain in place at present as there is room for improvement.Novangelis (talk) 17:57, 29 November 2011 (UTC)
I came here from Proteinogenic amino acid, and noticed a sudden change of reading-level. The "introduction and context" section of this page seems to be an attempt to provide context, but it is jarringly unrelated to the rest of the page. Given that the link here was from a sentence saying "The remaining two [proteinogenic amino acids not synthesized by the universal genetic code], pyrrolysine and selenocysteine, are incorporated into proteins by unique synthetic mechanisms", a good starting point for the introduction would be good to repeat some words to this effect here.

Well, I've seen worse. Yes, the "Introduction and context" seems to be borderline OR.
BTW, this is not as obscure as you think. This amino acid relates to methanogenic archaea, which may be a clue to the origin of life on earth, or elsewhere. Kortoso (talk) 00:17, 14 December 2013 (UTC)

Sorry, I'm not very good at editing and I don't know how to do citations or references — Preceding unsigned comment added by 140.226.169.99 (talk) 15:06, 16 April 2012 (UTC)

Yes check.svg Done Thank you for the suggestion. I have added it to the article. -- Ed (Edgar181) 15:12, 16 April 2012 (UTC)

Higher organism have heme[edit]

There are no doubts why higher organism don't produce pyrrolysine. They produce heme instead, like Porphyrin. Some guys need to do more research about this, so I can read it in the Wikipedia next time. --178.197.236.74 (talk) 16:24, 9 September 2013 (UTC)

Citations needed[edit]

"and one known bacterium in enzymes that are part of their methane-producing metabolism."

I would like very much if someone could give a citation that confirms this. It can be bad phrasing, but this make it look like there is at least one bacterium that has the machinery to synthesise methane, which I doubt. — Preceding unsigned comment added by Januoaxe (talkcontribs) 23:13, 9 November 2015 (UTC)
