3D Structures of Some Diarrheal Causing Bacterial Toxins.

摘要

The incorporation of data from additional heavy atom derivatives and the inclusion of anomalous dispersion data improved the electron density map markedly. The short alpha helix lying next to a segment of beta sheet resembles strikingly the structural motif in an MHC class I molecule binding site which also is believed to be present in class II molecules. This further reinforces our feeling that SEB map is biologically and biochemically reasonable.
