Figure 1: Comparison of the amino acid sequences around a catalytic site cysteine residue between MST and TST Sequence identity was analyzed using GENETYX (GENETYX CORPORATION). Box, a catalytic site. E, E. coli (D10496 for MST, NP_417883 for TST); H, Homo sapiens (BC009450 for MST, D87292 for TST); L. Leishmania (CAC85741); P1 and P2, Arabidopsis thaliana (AB032864 and AB032865 for MSTs); R, Rattus norvegicus (D50564 for MST, BC088449 for TST). Underlined amino acids, consensus sequences for MST or TST.
