[2DNMR]. (a) ¹H–¹³C HSQC of the extracellular form of marennine (EMn) in deuterated phosphate buffer. On top the corresponding 1D ¹H spectrum. The lines separate areas of carbons with—among others—two hydrogen atoms and with one or three hydrogens, as determined by an additional edited HSQC with lower resolution and signal-to-noise ratio; (b) Generic pyranose; (c) Ring region of a ¹H–¹H TOCSY of EMn with 90 ms mixing time. The strong ¹H signal at 3.65 ppm stems from an impurity.
