ANTARCTIC ICE ALGAE CPD PHOTOLYASE AND CODING GENE, EXPRESSION VECTOR AND APPLICATION THEREOF

摘要

Disclosed is an Antarctic ice algae CPD photolyase, a protein as set out in (a) or (b): (a) an amino acid sequence represented by SEQ ID NO:2; (b) a protein derivative of (a) having CPD photolyase activity, the amino acid sequence of which having been subjected to substitution, deletion or addition of 1 to 10 amino acid residues. Also disclosed are an Antarctic ice algae CPD photolyase coding gene and expression vector, and application of the Antarctic ice algae CPD photolyase in fields relating to cosmetics and biopharmaceuticals. The present invention clones the Antarctic ice algae CPD photolyase gene for the first time, successfully cloning said gene into the expression vector, and thereby obtaining a large quantity of CPD photolyase. The CPD photolyase has applications within fields relating to cosmetics and biopharmaceuticals, and may actively repair disorders caused by ultraviolet rays, thus being of great significance and benefit to society.
