GENERAL RESULTS

For the heavy metal AND we sent to the registry four Biological Parts: CI, and the three different ArsR and CzrA metal sensing repressors binding fused promoters (97, 98, and 99). We did not design promoter 98 (iGEM Newcastle 2009 did) however the part was not in the registry.
The constructs we have up to now are:
AmyE 5' +CzrA/ArsR (97 and 98)+ RBS P4 + RBS CI + RFP + TERMINATOR

We still need to complete them with Sp/Smr + TERMINATOR + AmyE 3' (a part which we already have), do do the same thing for promoter 99, and to add :
AmyE 5' +CzrA/ArsR (97 and 98)+ RBS LasR + RBS CI to RFP + TERMINATOR and Sp/Smr + TERMINATOR + AmyE 3' as well. We are also trying to ligate our fused promoters to GFP in order to characterize them.

For the arabinose-xylose AND gate we sent to the registry the omega cassette, pBad/pXyl, pVeg, and XylR. (XylR already existed in the registry, but ours is optimized for Bacillus subtilis). We characterized the omega cassette.

The constructs we have up to now are:
AmyE 5' + pBad/pXyl

RBS AraC + omega cassette + AmyE 3'

Pveg + RBS XylR (we are working hard to obtain the final construct which joins these two parts.

For the A3-LasB (GusA reporter) OR gate we sent to the registry A3.
We have:
RBS - GusA, AmyE 5’ digested with S, P, AmyE 3’ digested with E, X, A3 promoter digested with S, P, LasB promoter digested with S, P, B0014 digested with E,Xand Omega cassette – AmyE 3’.

AmyE 5' + LasB + RBS GusA Terminator and need to ligate it with A3 + RBS GusA Terminator + omega cassette terminator + AmyE 3' which we also already have.

Regarding our work with Bacillus subtilis, we designed a new standard for working with it. This way future iGEM teams that wish to work with Bacillus subtilis will not have trouble transforming it. We designed a series of videos to explain how this is done.
