The strand cutting proceeds through the covalent joining of a 3′ phosphate to a tyrosine of the integrase protein. Further efforts in this direction are desirable, not just for their intrinsic interest but also as models for viruses that infect eukaryotic hosts; for example, it is well documented that members of the coronavirus group, which has attracted attention recently through the emergence of a deadly new human pathogen that causes severe acute respiratory syndrome (SARS), undergo frequent recombination in nature 10, 11 .	./cache/cord-314642-oobbdgzh.txt	./txt/cord-314642-oobbdgzh.txt
