From: Widespread presence of "bacterial-like" PPP phosphatases in eukaryotes

Figure 5

Distinct conserved motifs in the C-termini of bacterial and "bacterial-like" PPP phosphatases from eukaryotes as opposed to archaeal and eukaryotic PPP phosphatases. A His residue directly binding a metal ion in the catalytic centre (marked with asterisk), and the elements of secondary structure are shown for bacteriophage λ phosphatase and for human PP1 according to ref. [20] and [19], respectively. The (I/L/V)D(S/T)G motif, highly conserved in bacterial and "bacterial-like" phosphatases, is highlighted. An expanded version of this alignment can be viewed as the Additional File 2.
