GFP
This is a new Silver-fusion compatible GFP BioBrick part. This particular GFP was previously mutated for improved fluorescence photostability (Crameri, 1996). The excitation and emission wavelengths for this GFP are 395 nm and 509 nm, respectively. That being said, GFP-positive cells emit a bright green fluorescence when exposed to shorter-wavelength UV light, such as on a transilluminator. See part BBa_K208045 for a functional composite part containing this GFP with a Lac promoter.
Usage and Biology
The Silver-fusion compatibility means that the prefix and suffix are slightly modified from the original BioBrick prefix and suffix. Specifically, a single base pair is removed from the prefix and suffix, directly next to the part.
The Silver prefix is: 5' GAATTC GCGGCCGC T TCTAGA 3'
The Silver suffix is: 5' ACTAGT A GCGGCCG CTGCAG 3'
The scar that is formed from ligating XbaI and SpeI between two fusion compatible parts is 5' ACTAGA 3', which is six base pairs long and does not contain a stop codon. Therefore, fusion of two proteins can occur by this method. Additionally, this part is still useful and functional for non-fusion applications. There are more design considerations for when using Silver BioBrick parts. See this description by the Silver lab for more information about <ahref="http://www.openwetware.org/wiki/Silver:_BB_Strategy">Silver fusion</a>
