NEB 10-beta E. coli, which lack the native fim switch (fimS) and known fim recombinases, were co-transformed with K1077007(amilCP j23100 fim switch) or K1077003(GFP j23100 fim switch), and K1077002 (aTc inducible fimE, HSL inducible hbiF) and plated on to LB plates with or without inducer. A) Close up of 3 colonies on a plate containing K1077007 and K1077002 co transformants. Three distinct phenotypes were observed: Solid Blue colonies(bottom left), Mixed colonies that had distinct white and blue regions(bottom middle), and Solid White colonies(top right). Therefore, the uninduced fim transcriptor in the context of K1077002 is subject to leaky fimE and/or hbiF activity. B) Quantification of the phenotypes observed on the plate in A. C) When induced with 4.32µM aTc and grown overnight (left) , no GFP is produced as expected due to induced fimE turning the switch OFF. When induced with 1µM HSL and grown overnight (right), GFP is produced as expected due to induced hbiF turning the switch ON.

As part of the 2013 CU Boulder project we worked on separating RFP from AmilCP and we measured the spectrum of AmilCP from 400 nm to 600 nm.

We also found that when running on an agarose gel RFP will run down on the gel while AmilCP runs up on the gel.

This part was employed in testing our Gibson Assembly protocol. In the experiment design, the mRFP coding DNA sequence in J04450 was replaced with that of amilCP. The resulting plate from transformation of the post-reaction mixture is shown. The color of the blue chromoprotein was clearly distinguished from that of mRFP, which aided in my evaluation of the performance of Gibson Assembly.

Our team has managed to couple this biobrick part with our promoters: alsT, fnr, and sboA. The cloning was done in BBa_K818000 (plasmid backbone for B. subtilis, engineered by team Groningen 2012), to allow color expression in B. subtilis. We utilized a strong RBS BBa_B0034 for pigment expression in E. coli and B. subtilis.

The purple/blue colour was strongly visible in E.coli without any induction, while the expression in B. subtilis was more subtle (B. subtilis colony looks slightly blue on the plate agar).

After induction of the promoter before AmilCP, B. subtilis also turned clearly purple/blue. Please have a look at the page of BBa_K818400 for more information.

We have observed that expression of amilCP confers a noticeable fitness cost in E coli. This is surprising, given that such behaviour is not seen in other homologous chromoproteins and fluorescent proteins. We thus recommend using the new aeBlue (BBa_K864401) chromoprotein for blue color expression, which also has a more clear blue color.
