Biological function
This gene, along with kilA, confers resistance to the chemical compound potassium tellurite (K2TeO3). The use of this gene as marker was developed to suit strains that were aimed to be released in field trials, where it is not desirable to use antibiotic resistance genes as marker tools for tracking the bacteria. Makes selective plating on potassium tellurite possible.
