Abstract
The structural relatedness of K88-related major and minor subunits was deduced from their sequences by hydrophobic cluster analysis (HCA) and secondary structure predictions produced by the profile neural network prediction program (PHD) on multiple sequence alignments. Although the weak residue identity between major and minor subunits is evidence of a high evolutionary distance, an overall structural similarity was observed. In addition, clear amphipathic conformations were conserved in predicted secondary structure. On the basis of this predicted structural similarity, a schematic 2D model of ClpG subunit was developedKeywords
