  • While environmentally friendly or so-called "green" chemistry has become all the rage in the chemical community, no human chemist can yet match what a single jellyfish gene directs: 238 ordered condensations + 1 cyclization + 1 oxidation, all done in a few minutes in aerated water with no protecting groups, only one slightly toxic byproduct, and essentially 100% yield of an extremely useful product that literally glows green.

  • The fluorescent moiety is an imidazolone ring structure that is formed by the posttranslational cyclization of a tripeptide, ser65-tyr66-gly67.

  • In diene synthesis the two chains attach themselves to four or two carbon atoms to form a ring, which thus contains six atoms; this number is particularly favourable to cyclization.

  • The problem is known as strand cyclization, but Hud and his team discovered that using a molecule that binds between neighboring base pairs of DNA, known as an intercalator, can bring short pieces of DNA and RNA together in a manner that helps them create much longer molecules.
