Alignment of wheat phytase to related PAPs in other plants: Orysa sativa, Medicago truncatula and Glycine max. The five conserved regions (black boxes) contain the seven invariant amino acids (bold) involved in coordination of the metals in the binuclear center (Klabunde et al., 1995). Asterisks (*) mark invariant amino acid residue between the aligned sequences and numbers to the right are residue numbers
