New BioBrick encoding an improved fluorescent protein

Green Fluorescent Protein (GFP) offers efficient and convenient means of visualising the dynamic process of gene expression and of obtaining readout of the current state of complex gene regulatory networks - features of major interest for synthetic biology.

Stefan Milde, working in the Haseloff Lab at Cambridge as part of iGEM2008  has constructed BioBrick versions of improved GFP variants and tested their properties (Parts:BBa I746908-I746919). He has compared two recently reported GFP variants to the mut3GFP variant in the Registry of Standard Biological Parts. The two GFP variants chosen were "superfolder GFP", developed and described by Pédelacq et al (2006), which was engineered for improved fluorescence in fusion proteins and P7 GFP ("superfast GFP") which was engineered by Fisher et al (2008) and selected on the basis of its very rapid folding in vitro.
