Figure 2: Model for the two α-helix dipoles of TST and MST, each structure is represented using RasMol. (a) bovine liver TST from 1DP2, red ribbon structure represents two helix-dipoles (α9 and α10) and ball-and-stick model in yellow represents a catalytic site Cys247. (b) Leishmania major MST from 1CKG red ribbon structure represents two helix-dipoles (α8 and α9), red ribbon structure represents two helix-dipoles (α8 and α9), and ball-and-stick model in yellow represents a catalytic site Cys253.
