Metal Sensing
Introduction
If our project is to process cadmium and not other metals, we need to genetically engineer Bacillus subtilis to carry out a set of cellular processes based on the action of metal sensors. These metal sensors will detect cadmium through a system known as AND Gating.
There are two metal sensing repressors, which are known to respond to cadmium: arsR and czrA. By placing binding sites to these two metal sensing repressors next to each other in a promoter region, the gene regulated by that promoter will be synthesized only when a combination of metals that bind to both sensors are present; this is a combinatorial approach for gene expression regulation.

18th August 2009 | Transformed DH5-alpha E. coli cells with BBa_J33206 from the Spring Distribution |
19th August 2009 | Inoculated 3 tubes of LB with 3 colonies of potential transformant E.coli cells |
20th August 2009 | Conduct mini-preps on the three overnight-grown cultures of potential BBa_J33206 transformants and digested them with restriction enzymes. |
21st August 2009 | Analysed digested BBa_J33206 mini-prep DNA by DNA gel electrophoresis and prepared midi-preps also. |
25th August 2009 | Concentrated (and ethanol precipitated) the BBa_J33206 Midi-prep sample. |
26th August 2009 | Digested BBa_J33206 midi-prep DNA with EcoRI and PstI and analysed through DNA gel electrophoresis - digest reaction not successful (a second attempt at digests needed) |
27th August 2009 | Digested pSB1A2 (containing BBa_J33206 BioBrick) |
