a Key COSY/NOESY/TOCSY and (b) HMBC correlations are highlighted in the structure of KmcB. c Structures of KmcA-C with varying substitution patterns and assignment of the chiral centers. d 1H-13C HSQC section of KmcB with chemical shift ranges from 5.10–5.23 ppm (1H) and 90.5–99.0 ppm (13C) (DMSO-d6, 298 K). The cross peaks belonging to the anomeric carbons within the mannose moieties in both KmcB (blue) and minor KmcB’ (red) are annotated.
