Extended Data Fig. 5: Conversion of purified 5 to 4.
From: Mutanofactin promotes adhesion and biofilm formation of cariogenic Streptococcus mutans
a, A proposed mechanism for the conversion of 5 to 4, accompanying the release of l-lactic acid (6). b, LC–HRMS extracted ion chromatogram trace of the degraded 5. EIC + = 89.02 ± 0.01, 606.21 ± 0.01, and 696.24 ± 0.01, which correspond to compounds 6, 4, and 5, respectively. Negative ion mode, LC–MS measured accurate mass spectrum was recorded across the range 50–1000 m/z.
