Multiple sequence alignment of SseA, bovine and A. vinelandii rhodanese enzymes (accession Nos. P31142, P00586 and P52197, respectively). Residues assuming β-strand and α-helix conformation in the two TST structures (PDB entries 1rhs and 1e0c , respectively) are shown with gray and black backgrounds, respectively. Asterisks indicate conserved amino acids. Active-site loop residues are included in a box. Conventional labels for secondary-structure elements (Bordo et al., 2000 ![]() ![]() |
