Figure 4From: Disruption of rimP-SC, encoding a ribosome assembly cofactor, markedly enhances the production of several antibiotics in Streptomyces coelicolorActivity analysis of catechol dioxygenase in E. coli . (A) Growth curve of four different E. coli strains. (B) Activity analysis of the wild-type or mutated catechol dioxygenase. Data were presented as the averages of the results of three independent experiments in triplicate. Error bars showed standard deviations. The asterisk (*) indicates mutated catechol dioxygenase (UGG codon as tryptophan at 47 position was replaced by UGA as stop codon).Back to article page
