Аннотация: Site-directed mutagenesis is a powerful tool to investigate the structure-function relationship of proteins and a function of certain amino acid residues in catalytic conversion of substrates during enzymatic reactions. Hence, it is not surprising that this approach was repeatedly applied to elucidate the role of certain amino acid residues in various aspects of photoprotein bioluminescence, mostly for aequorin and obelin, and to design mutant photoproteins with altered properties (modified calcium affinity, faster or slower bioluminescence kinetics, different emission color) which would either allow the development of novel bioluminescent assays or improvement of characteristics of the already existing ones. This information, however, is scattered over different articles. In this review, we systematize the findings that were made using site-directed mutagenesis studies regarding the impact of various amino acid residues on bioluminescence of hydromedusan Ca2+-regulated photoproteins. All key residues that have been identified are pinpointed, and their influence on different aspects of photoprotein functioning such as active photoprotein complex formation, bioluminescence reaction, calcium response and light emitter formation is discussed.
