We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

Background

Osamu Shimomura, Martin Chalfie and Roger Y. Tsien shared the 2008 Nobel Prize in Chemistry for their for the discovery and development of the green fluorescent protein, GFP.
GFP is small protein (21 kDa) and does not require cofactors to become fluorescent.

The crystal structure of GFP ^[1]^[2] is an eleven-stranded anti-parallel beta- barrel, threaded by an alpha-helix, running up along the axis of the cylinder.

The chromophore is in the distorted alpha-helix that runs along the axis of the can, close to the center of the can-like cylinder.

You can take a close look at the of GFP in the PDB entry 1ema.
