a

+, normal [PSI+] propagation; -, loss-of-[PSI+]; ±, weak [PSI+] propagation

b

The assessments were evaluated by three independent experiments. -, loss-of thermotolerance; ±, weak thermotolerance; +, normal thermotolerance.

c

The frequency of amino acid conservation at the indicated positions in S. cerevisiae Hsp104 relative to T. thermophilus ClpB, E. coli ClpA and ClpB, A. thaliana Hsp101 and S. cerevisiae Hsp78. Alignments refer to Lee et al.6

d

History about each mutations: N, newly engineered in this laboratory including those of very recent publication;27 M, mutations reported in the literature as multiple amino acid substitutions and each mutation not clarified independently; T, mutations known to affect only thermotolerance; B, mutations known to affect both thermotolerance and [PSI+].
