RECOMBINANT THERMOSTABLE LUCIFERASE, METHOD FOR PRODUCTION THEREOF, ISOLATED NUCLEAR ACID, EXPRESSING VECTOR, KIT FOR BIOLUMINESCENT ASSAY, ANALYTICAL TEST FOR CoA DETECTION IN THE SAMPLE

摘要

FIELD: gene and protein engineering for various luminescent assays.;SUBSTANCE: new luciferase mutant forms have been obtained. Said mutant forms have increased thermostability and optionally different emission wave length in contrast with respective wild type enzymes. In all disclosed muteins natural amino acid residue in position equivalent to 357-position in Photinus pyralis luciferase sequence is replaced with other residue, preferably with uncharged polar amino acid (in particular tyrosine) residue. Mutant luciferases of present invention are useful in various analytical systems as reporter agent.;EFFECT: Mutant luciferases with new properties.;22 cl, 15 dwg, 6 tbl, 12 ex
