The changes in the reduction potential of Pseudomonas aeruginosa and Alcaligenes denitrificans azurins and spinachplastocyanin following point mutations and residue ionizations were factorized into the enthalpic and entropiccontributions through variable temperature direct electrochemistry experiments. The mutational variations of thereduction enthalpy and entropy were analyzed with a QSPR (Quantitative Structure-Property Relationships) approach,employing global and local theoretical descriptors defined and computed on the three dimensional protein structure.
