Welcome
Welcome to the Rice [http://icampus.mit.edu/projects/iGem.shtml International Genetically Engineered Machine (iGEM)] Team Wiki. We are participating in the iGEM Competition for the first time so we are in the process of building our team. Currently, we are developing a 'quorumtaxis' system, which integrates the quorum-sensing and chemotaxis systems. Bacteria engineered with this quorumtaxis system will be able to move towards high concentrations of quorum pheromone. The Rice iGEM Team is divided into three groups: Experimental, Theory, and Modeling. Explore our website or contact us, as we will be constantly updating with the latest developments in the project.

PROJECT PROPOSAL
Quorumtaxis -- The integration of quorum-sensing and chemotaxis pathways, to produce an E. coli strain which is capable of detection and movement towards concentrations of the B. subtilis quorum phermone, ComX. Upon successful quorumtaxis towards the target, the E. coli will produce a signaling response (e.g., GFP production) or a kill response (e.g., the expression of gram-positive lethal proteins). A detailed propsal outline is provided in the link below.
EXPERIMENTAL GROUP
Welcome! The Rice iGEM E-group is tasked with the construction of a wholly novel phenotype -- 'quorumtaxis'. More about the specifics of this project can be found in the 'Project Proposals' section of the Rice iGEM page. Currently, we have 6 undergraduate students working on this project, with two graduate students as advisors.
Experimental Work
MODELING GROUP
The mission of the modeling groups is to help completely characterize "Quorumtaxis" for use as a biobrick. This means characterizing the transfer function, latency, etc. In our method, comX particles will act as an atractant that will effect the chemotaxtic pathway via the chimeric comP/MCP membrane protein. Therefore, in order to model this event, we will focu on modeling chemotaxis within bacteria. We have identified the following goals.
- Model the response of a single bacterium to stimulus
- Model the phenotypic response of a bacterial colony
- Understand the effect of a comP/MCP chimeric protein on the chemotaxtic pathway
- Develop a theoretical framework of integrating the kill response in a single bacterium
- Simulate the kill behavior for a bacterial colony
