摘要：

In Corynebacterium glutamicum, the transcriptional regulator RamB negatively controls the expression of genes involved in acetate metabolism. Here we show that RamB represses its own expression by direct interaction with a 13-bp motif in the ramB promoter region. Additionally, ramB expression is subject to carbon source-dependent positive control by RamA.
