Partial 600-MHz ¹H-¹³C HSQC spectral comparison of the pathogenic B. cereus and B. anthracis secondary cell wall SCWPs. The ring proton regions are compared for (A) B. cereus G9241 SCWP ¹H-¹³C HSQC ring proton region; (B) B. anthracis Sterne 34F₂ SCWP ¹H-¹³C HSQC ring proton region. The B. cereus G9241 spectrum is virtually identical with that of B. anthracis Sterne, apart from the appearance of new signals present in the B. cereus G9241, including variant forms of residues G and D (yielding G + G′ and A/A′) and six new signals arising from residue F (α-Galp).
