WebJul 6, 2016 · To unravel the structural mechanism underlying OsCEBiP recognition of chitin elicitor, we solved the crystal structure of OsCEBiP-ECD in complex with a chitin tetramer (Table 1). The three LysMs pack tightly against each other with the CRD anchoring to LysM1, and the chitin tetramer (NAG) 4 only binds to LysM2 ( Figure 1 F). WebA detailed model for the crystal structure of the fibrous polysaccharide chitin is proposed. The structure determination has been carried out by using an optical analogue instrument which proved to be an adequate and rapid tool for the derivation of Fourier transforms, signs of amplitudes and the production of optical Fourier syntheses.
