CTPS has indeed been explored as a potential therapeutic target for a number of infections, especially Mycobacterium tuberculosis (Mori et al., 2015; Esposito et al., 2017; Chiarelli et al., 2018), but also for protozoan infections including trypanosomiasis (Fijolek et al., 2007). The gene discussed is CTPS1; the disease is trypanosomiasis.
