Identification of Pentatricopeptide Repeat Proteins in the Model Organism Dictyostelium discoideum

Figure 2

Amino acid sequence alignment of PtcK from D. discoideum (Dd) with ubiquitin hydrolases (UBHs) from other organisms. Sequences used in the alignment include UBHs from Homo sapiens (Hs, accession number NP_005993), Mus musculus (Mm, accession number AAF64193), Bos Taurus (Bt, accession number NP_001035631), Glomerella graminicola (Gg, accession number EFQ25707), Saccharomyces cerevisiae (Sc, accession number EDN63415), and WTF1, a PORR-containing protein from Zea mays (Zm, accession number ACI96105). Only the relevant portion of the alignment is shown. Boxed residues indicate conserved amino acids required for ubiquitin hydrolase activity while identical (*), conserved (:), and semiconserved (.) amino acids are also denoted.
