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.
多形拟杆菌硫酸软骨素利用(csu)基因的表达受硫酸软骨素调控。然而,我们现在发现,csu基因并非都以相同方式受到调控。特别是,编码β-葡萄糖醛酸酶的基因(csuE)在两种不同条件下表达,而这两种条件不会导致其他csu基因的表达。
