(a) Schematic representation of the 100 bp deletion in the S. anginosus ∆ccpA strain. The site of deletion is marked with black lines and the deleted base pairs in bold. The 100 bp deletion results in a frameshift and a premature stop codon (*). (b) Effect of glucose supplementation on SLS promoter activity. The activity of the SLS promoter was determined using an EGFP reporter plasmid. The relative mean fluorescence intensity (MFI) of cells grown in THY medium supplemented with the indicated glucose concentrations is shown in comparison to the positive control. Negative control: S. anginosus pBSU409; positive control: S. anginosus pBSU409::cfbprom; WT: S. anginosus type strain; ΔccpA: S. anginosus ΔccpA strain. The mean values and standard deviations of five independent experiments are shown. Mann-Whitney-U test was performed to illustrate significant difference to S. anginosus pBSU409::sagprom (p < 0.05).
