Abstract

Methyl accepting chemotaxis proteins have been identified in R. sphaeroides. One is targeted to previous septation sites under heterotrophic growth conditions, while a second constitutive MCP is localised cytoplasmically. 1. The genes for these MCPs will be cloned and sequenced. 2. They will be mutated in frame and the ones targeted to different locations identified by immunoelectron microscopy. 3. The sequences will be compared and the possible sites involved in targeting identified and altered by site directed mutagenesis. 4. Transcriptional and translational fusions will be made and their expression under different environmental control identified. 5. Signals controlling expression will be identified by transferring known mutations in oxygen sensing proteins into the R. sphaeroides cells carrying fusions. 6. Sites acting as targets will be characterised.
