Abstract

The general model for the control of prokaryotic plant cell wall hydrolases is that constitutive enzymes release small saccharides that enter the bacterial cytoplasm and bind to regulatory proteins modulating their activity. Preliminary data suggest that signalling cascades culminating in hemicellulase expression in the bacterium Cellvibrio cellulosa are activated by molecular inducers to membrane bound sensor proteins. The aim of this project is to: 1) test the hypothesis that two-component systems are key elements in bacterial hemicellulase expression; and 2) to identify the molecular inducers binding that activate the signalling cascades that culminate in hemicellulase expression. Resolution of this latter question will establish whether each signalling cascade is activated by one or range of different molecular cues and will determine to what extent there is cross-talk between the different regulatory circuits.
