Monday's Molecule #210

Last week's molecule was the "go" conformation of the leader sequence in the E. coli trp operon. The winners were Rosie Redfield and Quyen Huynh. [Monday's Molecule #209].

Today's molecule isn't very complicated but it has a big effect. You need to be very specific in identifying the exact molecule shown in the figure. I won't accept answers that are ambiguous.

Email your answers to me at: Monday's Molecule #210. I'll hold off posting your answers for 24 hours. The first one with the correct answer wins. I will only post mostly correct answers to avoid embarrassment. The winner will be treated to a free lunch.

There could be two winners. If the first correct answer isn't from an undergraduate student then I'll select a second winner from those undergraduates who post the correct answer. You will need to identify yourself as an undergraduate in order to win. (Put "undergraduate" at the bottom of your email message.)
