Summary

Automatic Translation

Bacillus anthracis er det obligatoriske patogen af ​​dødelig inhalationsbrandbrand, så undersøgelser af dets gener og proteiner er strengt regulerede. En alternativ tilgang er at studere orthologe gener. Vi beskriver biofysikologiske undersøgelser af en B. anthracis ortholog i B. cereus , bc1531, der kræver minimal eksperimentelt udstyr og mangler alvorlige sikkerhedshensyn.
