Figure 8. Model structure of intact CBH I as deduced from the results of small angle X-ray scattering experiments (17). The arrow indicates the proteolytic scission site (papain), dividing the core-protein (left) from the binding domain (right). A, A-domain B, B-domain N, N-terminus C, C-terminus.

However, the results of small-angle X-ray scattering experiments on iron-labelled networks have not entirely confirmed the above results for a given network the product d Q ll3 is not found to be a constant. The reason for this discrepancy is yet unknown. 

The precise structural nature of the CL/DNA complexes is elucidated in high resolution synchrotron small-angle X-ray scattering (SAXS) experiments carried out at the Stanford Synchrotron Radiation Laboratory (Raedler et al., 1997 Salditt et al., 1997, 1998 Koltover et al., 1999 Lin et al 2000).
