Table 1.

rmsd values between different STP structures. Monomers A and D of SaSTP as well as the core β sheet of monomer A are compared with A monomers of HsSTP (PDB code 1A6Q), MtSTP (PDB code 1TXO), and TxSTP (PDB code 2I44). The rmsd calculations were carried out using SSM alignment program [38]. Values in parentheses show the number of aligned residues.

	MtSTP (Å)	HsSTP (Å)	TxSTP (Å)
SaSTP (A)	1.82 (223)	2.31 (212)	2.05 (208)
SaSTP (D)	1.78 (223)	2.24 (209)	2.19 (207)
SaSTP (A) β sheet only	1.21 (70)	1.49 (70)	1.16 (62)
