Enzyme cascade hypothesis
WebA ‘signal transduction cascade’ hypothesis for Chi’s regulation of wild-type RecBCD enzyme Based on these and other observations, especially the RecBCD crystal structure and its interpretation ( Singleton et al. 2004 ), we propose the following hypothesis for Chi’s regulation of wild-type RecBCD enzyme ( Fig. 5 ).
