Evidence for differential regulation of genes in the chondroitin sulfate utilization pathway of Bacteroides thetaiotaomicron.

V Hwa1, A A Salyers.   

Abstract

Expression of the chondroitin sulfate utilization (csu) genes of Bacterioides thetaiotaomicron is regulated by chondroitin sulfate. We have now found, however, that the csu genes are not all regulated in the same way. In particular, the gene encoding beta-glucuronidase (csuE) is expressed under two different conditions that do not lead to expression of other csu genes.
