LacI IS mutants

Based on atomic structures of LacI and evidence from genetic studies we have constructed a set of eight mutants of LacI, which are unresponsive to IPTG or lactose and are a useful component of genetic circuits or pulse generators. Qualitative genetic experiments were conducted to estimate the strength of repression exerted by the LacI IS mutants and the mutants were found to repress expression from lac-controlled promoters even at 10mM IPTG. We have provided the LacI IS mutants by themselves (BioBricks [http://partsregistry.org/wiki/index.php?title=Part:BBa_K142000 K142000] through [http://partsregistry.org/wiki/index.php?title=Part:BBa_K142007 K142007]) and with RBS and terminator (BioBricks [http://partsregistry.org/wiki/index.php?title=Part:BBa_K142008 K142008] through [http://partsregistry.org/wiki/index.php?title=Part:BBa_K142015 K142015]) for straigthforward integration into genetic circuits.

Ribosome Modulation Factor (RMF)

We have introduced RMF as a new BioBrick ([http://partsregistry.org/wiki/index.php?title=Part:BBa_K142040 BBa_K142040] and [http://partsregistry.org/wiki/index.php?title=Part:BBa_K142041 K142041]). Based on extensive literature search as well as our own biophysical experiments we concluded that RMF would among other uses be helpful as "pause switch", since it terminates protein expression rapidly without killing the cell.

Analysis, modeling, and simulation of BioBrick Parts or Devices

We propose a novel method of random gene deletion and chemostat-based selection of species with a reduced genome. For this we provide an algorithm described here.
