WebJun 5, 2015 · Standard triple resonance backbone assignment of proteins is based on the CBCANNH and CBCA (CO)NNH spectra. The idea is that the CBCANNH correlates each NH group with the Cα and Cβ chemical shifts of its own residue (strongly) and of the residue preceding (weakly). The CBCA (CO)NNH only correlates the NH group to the preceding Cα … WebAfter solid-state fermentation of wheat straw with five lignocellulose-degrading fungi, lignin was extracted and studied by CPMAS 13C NMR. The increase in the intensity of the signals in the 200-164 ppm range is evidence for the oxidative alteration of lignin. The lignins degraded by the white-rot fungi Ganoderma australe and Phanerochaete chrysosporium …
