Monomeric Red Fluorescent Protein from Discosoma striata

Mutant of the Biobrick BBa_E1010. In order to make it compatible with the Freiburg-Standard RFC25, two AgeI-Restriction sites were deleted.

monomeric RFP: Red Fluorescent Protein.

Excitation peak: 584 nm Emission peak: 607 nm

Usage and Biology

This part was created in order to enhance the [http://2012.igem.org/Team:LMU-Munich/Bacillus_BioBricks Bacillus BioBrick Box] by adding different fluorescent proteins in order to have more reporters available in B. subtilis. It still works very well in E. coli; the rather weak coloring you see on the pictures is due to the fact that a B. subtilis expression vector (pBS0K-Pspac) which shows a rather weak and heterogenous expresion was used in E. coli

The left eppendorf tube contains a pink bacterial pellet of E. coli containing the BioBrick BBa_K1351021 in pBS0K-pPspac, a B. subtilis expression vector. On the right, you can see E. coli with the empty vector

Design

This part was generated in a modified version of RFC25, where a strong Shine Dalgarno Sequence (SD) is included, and has the following prefix and suffix:

prefix with EcoRI, NotI, XbaI, SD and NgoMIV:	GAATTCGCGGCCGCTTCTAGAGTAAGGAGGAGCCGGC
suffix with AgeI, SpeI, NotI and PstI:	ACCGGTTAATACTAGTAGCGGCCGCTGCAG

Sites of restriction enzymes generating compatible overhangs have the same color:

EcoRI and PstI in blue, NotI in green, XbaI and SpeI in red, NgoMIV and AgeI in orange. Shine-Dalgarno sequence and stop codons are underlined.

This part is used in the 2014 LMU-Munich iGEM project [http://2014.igem.org/Team:LMU-Munich BaKillus].

BioBrick AutoAnnotator

Protein data table for BioBrick BBa_ automatically created by the BioBrick-AutoAnnotator version 1.0

Nucleotide sequence in RFC 25, so ATGGCCGGC and ACCGGT were added (in italics) to the 5' and 3' ends: (underlined part encodes the protein)
ATGGCCGGCATGGCTTCC ... ACCTGTGCTACCGGT
ORF from nucleotide position -8 to 681 (excluding stop-codon)
