This is a simple one. All you have to do is give the correct name of the residue in the middle of the picture.
There's a direct connection between this molecule and Wednesday's Nobel Laureate(s). Your task is to figure out the significance of today's molecule and identify the Nobel Laureate(s) who are responsible for that significance. (Hint: There's also a connection to last week's lecture in biochemisty.)
The reward goes to the person who correctly identifies the molecule and the Nobel Laureate(s). Previous winners are ineligible for one month from the time they first collected the prize. There are three ineligible candidates for this week's reward. The prize is a free lunch at the Faculty Club.
Send your guess to Sandwalk (sandwalk(at)bioinfo.med.utoronto.ca) and I'll pick the first email message that correctly identifies the molecule and the Nobel Laureate(s). Correct responses will be posted tomorrow along with the time that the message was received on my server. I may select multiple winners if several people get it right.
UPDATE: There is no winner this week. Nobody got the residue and nobody guessed the name of the Nobel Laureate(s).
