FIG. 3.

Helical wheel analysis of the predicted coiled-coil region (residues 44 to 72) by the algorithm of Wolf et al. (63). At the end of the potential coiled-coil region are localized the two cysteine residues. Hydrophobic amino acids (squares), represented by one-letter code, are predominantly aligned at the a and d positions, surrounded by hydrophilic amino acids at other positions. At the e and g positions we found glutamic and lysine residues predominantly. Position numbers of the amino acids in the complete sequence of the 14-kDa protein are indicated.
