FIGURE 1.

Sequence similarity prediction of b-subunits. Arbitrarily selected b-subunit sequences of bacterial, cyanobacterial, and plant F₀F₁-ATP synthases were aligned using the ClustalW alignment series (78). Different degrees of amino acid identity or homology are implied by different shades of coloring. For better legibility, the sequences in the figure were truncated after the last E. coli amino acid.
