Amino acids in the catalytic domains of TS and TS-Like genes from <i>T. congolense</i> involved in enzymatic activities^*.

*The indicated amino acids have been selected based on structural [18] and mutation [19][23] studies with T. cruzi TS and on the sequence alignment of TconTS1b with T. cruzi[14]. Amino acid positions have been numbered based on the consensus of alignment (Figure 1) or starting methionine of each ORF.
