Repression of the TreR transcriptional regulator in Streptococcus mutans by the global regulator, CcpA.

abstract：:Actinobacteria are known by their ability to produce several antimicrobial compounds of biotechnological interest. Thus, in this study, we isolated and identified by partial 16S RNA sequencing ∼100 actinobacteria isolates from guarana (Paullinia cupana) bulk soil. Besides, we isolated from the actinobacteria Streptomy...

abstract：:DNA from Aspergillus sp. has been reported not to contain 5-methylcytosine. However, it has been found that Aspergillus nidulans responds to 5-azacytidine, a drug that is a strong inhibitor of DNA methyltransferases. Therefore, we have re-examined the occurrence of 5-methylcytosine in DNA from Aspergillus flavus by us...
