This research aims to identify and analyze new genes responsible for autoinducer production in bacteria.
Constructed V. harveyi reporter strains to detect autoinducers AI-1 and AI-2.
Analyzed the luxS gene from various bacteria species for homologous sequences.
Investigated the frameshift mutation in E. coli DH5alpha affecting AI-2 production.
Identified luxS genes in V. harveyi, S. typhimurium, and E. coli, defined as a new family of genes.
E. coli DH5alpha can produce AI-2 when complemented with the luxS gene from V. harveyi or E. coli O157:H7.
Analyzed luxSE.c. gene showed a frameshift mutation leading to a truncated protein.
