Diagrams corresponding to the three-dimensional structure of α-sarcin (A) and its amino-terminal β-hairpin (B) constructed from the atomic coordinates deposited in PDB (Protein Data Bank; reference 1DE3). Images were generated by the molmol program (Koradi et al. 1996). Residues corresponding to loops in A are: loop 1 (black), 38–49; loop 2 (light grey), 53–93; loop 3 (grey), 98–119; loop 4 (black), 126–132; loop 5 (light grey), 139–143.
