Beyond tellurite: the multifunctional roles of genes annotated as tellurium resistance determinants in bacteria

are relatively common in genome annotations and that they are frequently described as "tellurium resistance genes". We synthesized the literature to describe the functions of these ubiquitous genes beyond tellurium resistance. These genes have functions in diverse cellular processes including phage resistance, antibiotic resistance, virulence, oxidative stress resistance, cell cycle regulation, metal resistance, and metalation of exoenzymes. Considering this analysis, we propose that it is time to appreciate the multifunctional nature of the "tellurium resistance genes".
