Comparative protein structure

Figure 1 The basis of comparative protein structure modeling. Comparative modeling is possible because evolution resulted in families of proteins, such as the flavodoxin family, modeled here, which share both similar sequences and 3D structures. In this illustration, the 3D structure of the flavodoxin sequence from C. crispus (target) can be modeled using other structures in the same family (templates). The tree shows the sequence similarity (percent sequence identity) and structural similarity (the percentage of the atoms that superpose within 3.8 A of each other and the RMS difference between them) among the members of the family.

Comparative Protein Structure Modeling VIII. CONCLUSION... 

We are grateful to Dr. Azat Badretdinov and Mr. Eric Feyfant for many discussions about comparative protein structure modeling. AF is a Burroughs Wellcome Fellow. RS is a Howard Hughes Medical Institute predoctoral fellow. FM is a Norman and Rosita Winston Biomedical Research Foundation Fellow. AS is a Sinsheimer Scholar and an Alfred P. Sloan Research Fellow. The investigations have also been aided by grants from NIH (GM 54762) and NSF (BIR-9601845).
