In the first two columns the wild-type protein name and the protein length are reported. In the fourth column, the name of the mutant is reported. Columns 3 and 5 report optimal functional temperatures of the wild-type and the mutated sequence, respectively; Tm when present refers to the melting temperature; column 6 reports the mutated residues. In the case of Dmeh, the two mutants have 39 and 40 mutated residues, respectively (Shah et al., 2007). The considered proteins are: Shble: bleomycin-binding protein from the mesophilic bacterium Streptoalloteichus hindustanus (Brouns et al., 2005); Dmeh: Drosophila melanogaster engrailed homeodomain (Shah et al., 2007); β-GUS: β-glucuronidase (Xiong et al., 2007); BsCSP: cold shock proteins from Bacillus subtilis (Max et al., 2007); EcHPH: Escherichia coli hygromycin B phosphotransferase (Nakamura et al., 2005); PTDH: phosphite dehydrogenase from Pseudomonas stutzeri (Johannes et al., 2005; McLachlan et al., 2007) CbADH: Clostridium beijerinckii alcohol dehydrogenase (Goihberg et al., 2007); FAOX: fructosyl-amino acid oxidase from Corynebacterium sp. (Sakaue and Kajiyama, 2003); pDAO: porcine kidney D-amino acid oxidase (Bakke et al., 2006); PhyA: 3-phytase A from Aspergillus niger (Zhang and Lei, 2007).
