Abstract:
Major results of the use of protein engineering methods in studies of calcium-binding proteins with the highest affinity for calcium and known three-dimensional structure (parvalbumin, calmodulin, troponin C, calbindin, recoverin, alpha-lactalbumin, and others) are presented. Specific features of recombinant calcium-binding proteins are discussed. Experiments with genetic introduction of fluorescent probes, tryptophan and tyrosine, into proteins are overviewed. Effects of mutations in different parts of protein molecules (calcium-binding loops, hydrophobic core, and others) on their structure and properties and attempts of creation of artificial calcium-binding sites are discussed.

The Ca2+-CaM complex does not have enzymatic activity by itself. Instead, the complex binds downstream target proteins, including membrane proteins or enzymes,...
Conserved Binding Sites
Binding sites are often located in large pockets, and if their location on a protein’s surface is unknown, it can be predicted using various approaches. The energetic method computationally analyses the...
Ligand Binding Sites
Protein-ligand interactions are quite specific; even though numerous potential ligands surround a cellular protein at any given time, only a particular ligand can bind to that protein. Moreover, a ligand binds only to a dedicated area on the surface of the protein, known as the...
