Kill-Switch inducable with AI-2

Introduction

FlavoFlow

Vilnius-Lithuania iGEM 2020 project FlavoFlowincludes three goals towards looking for Flavobacterium disease-related problems’ solutions. The project includes creating a rapid detection kit, based on HDA and LFA, developing an implement for treating a disease, and introducing the foundation of edible vaccines. This part was used for the second goal- treatment - of the project FlavoFlow.

Biology

Quorum sensing (QS) is a communication system, which controls gene expression in response to population density, between bacteria. There are two QS systems: the first one, based on AI-1 or acyl-homoserine lactone (AHL), and the second – autoinducer 2 [1].

AI-2 - interconverting molecules, which are derived from the same precursor and called the „universal“ bacterial signal [1], [2], [3]. AI-2 controls the expression of LuxS regulated transporter, which is responsible for incorporation, phosphorylating, and processing of the AI-2 signal. The lsr transporter has genes, which expression is regulated by AI-2. LsrR is a repressor of the lsr operon. The AI-2, phosphorylated by lsrK, leads to derepression of lsr operon [4].
