TS is essential for DNA replication and repair[1]. In protozoa, dihydrofolate reductase (DHFR) and TS are expressed as a bifunctional monomeric enzyme (DHFR-TS) with the DHFR entity at the N terminal. DHFR and TS catalyze consecutive reactions in the dTMP biosynthesis. There are two different types of TS – ThyA and ThyX. The types differ in their activity and structure. The TS ThyX are flavin-dependent enzymes. Relevance TS inhibition at its folate-binding site is used in anticancer therapeutic drugs. DHFR-TS inhibitors are potential drug targets against parasite-transferred diseases. TS exhibits oncogene-like activity.[2] Structural highlights TS [3].
