Streptococcus gordonii and Veillonella atypica, two early-colonizing members of the dental plaque biofilm, participate in a relationship that results in increased transcription of the S. gordonii gene amyB, encoding an alpha-amylase. We show that the transcription factor CcpA is required for this interspecies interaction.
戈登氏链球菌和非典型韦荣氏菌是牙菌斑生物膜早期定植的两种细菌,它们之间存在一种相互作用,导致编码α-淀粉酶的戈登氏链球菌基因amyB的转录增加。我们发现,种间相互作用需要转录因子CcpA。
