monomeric RFP optimized for bacteria
mRFP1-derived, altered to be a BioBrick by removing a PstI site and adding BioBrick ends. [mRFP1 was itself a derived from DsRed (via 33 mutations!)]
mCherry is one of several "second-generation" monomeric fluorescent proteins developed in Roger Tsien's laboratory at UCSD (cf., Nature Biotechnology 22, 1567 - 1572 (2004). PMID 15558047

Some strange experimental results that have been seen could be explained by an internal RBS + start. The 10th amino acid is a Met which is preceded by AGGAGGA(NNNN). This is almost a perfect consensus RBS so it seems quite likely that translation can begin 10 amino acids in. Note that mCherry was designed by fusing the N and C terminal regions of EGFP on to a mRFP variant (to increase tolerance to protein fusions). Thus, removing the first several amino acids is not expected to have much effect on fluorescence. If this is truly a strong internal RBS, then the identity of any attached RBS may have little effect.
