- Normal cell growth and DNA rearrangement
- Sporulation triggered
- Start
- Spores take up metal (yes/no?)
- DNA rearrangment
- smtA metallothionein expression plus protein tag
- Cadmium is taken in through the mntH influx pump
- Is Cd Present?
- Cell enters the first stochastic switch
- Cell enters the second stochastic switch
- cadA rendered inactive
- smtA metallothionein sequesters Cd2
- smtA metallothionein incorporated into spore
- ger gene rearranged germination can't happen
- Expression of DNAase to prevent any chance of germination
- Finish
- GFP system
