Figure 2
Multiple sequence alignment of the cysteine synthase sequences from T. cruzi, L. infantum and T. theileri. Identical residues are displayed in red boxes and similar residues in red text; similar or identical residues are framed in blue boxes. The secondary-structure annotation is based on the TcCS structure presented here. Residues involved in catalytic activity are indicated by stars. SAT interaction residues are indicated by dots. The PLP box residues are outlined by a black box. |
