Antibiotic resistance has been observed with trimethoprim, a synthetic antibiotic used clinically to inhibit the chromosomal dihydrofolate reductase enzyme (cDfr) found in bacteria. Resistance to trimethoprim has been associated with type A and type B dihydrofolate reductases (DfrAs and DfrBs). Where DfrAs are mutants of cDfr, DfrBs are not related to cDfr, genetically and structurally. Using metagenomic data, five non-characterized proteins have been identified as distant homologs to DfrBs (DfrBHs), were they all have a predicted structural homology with the DfrBs. The goal of the project is to elucidate the evolutionary origin of members of the DfrB family and understanding their various properties such as resistance to trimethoprim and dihydrofolate reductase activity.
