The antitumor ¦Â-D-glucan[I,(1¡ú3)-linked with a D-glucosyl group attached to position 6 of alternate units] produced by S.sclerotiorum IFO 935 afforded a gel in neutral aq.soln.which gave no 13C-NMR signals. Signals appeared on the addu to the gel of NaoH to 0.5M and the linewidth was narrowest near 0.25M base(get-to-sol transition).I bound to Congo Red and shifted the ¦Ëmax in a manner similar to that of curdlan. Neutralization of the sol regenerated the magic-angle-spinning) 13C-NMR spectra,esp the signals for C-3 which appeared at 86 and 89 ppm resp. The c.p-m.a.s spectrum of regenerated І was similar to that of curdlan,suggesting a helical structure.Thus,I and regenerated I appear to have different conformations. |
