RBS+ydcE

ydcE which is also named as ndoA, encoding an RNase, namely EndoA. Being in the same RNase family with MazF/ChpAK/PemK, YdcE - the endoribonuclease ydcE encodes - can inactivate cellular mRNAs by cleaving them at specific but frequently occurring sites (i.e. UAUAAU↓AC). Thus, overexpression of EndoA can lead to programmed cell death or unhealthy conditions, depending on the amount of EndoA. Note that ydcE(ndoA) is demonstrated functional both in E. coli and B. subtilis. (Pellegrini et al., 2005)

Characterization by UCAS iGEM 2016 team

This summer we used the ydcD and ydcE genes to build a kill-switch. By measuring the growth curve of E. coli expressing toxin, we showed that toxin EndoA can effectively impede the growth and cleavage of E. coli.

We also characterized antitoxin ydcD, and documented the interaction between toxin and antitoxin on the page: BBa_K733003
