Partial comparison of the amino acid sequences of PDC proteins from Arabidopsis and orthologs in other species. Partial amino acid sequence alignments of PDC proteins from Zymomonas mobilis (ZymPDC; GenBank no. M15368), tobacco (NtPDC2; GenBank no. X81855), and Arabidopsis (AtPDC1, AT4G33070; AtPDC2, AT5G54960; AtPDC3, AT5G01330; and AtPDC4, AT5G01320). Active site is highlighted with asterisk. Alignments were generated using the Multalin software v5.4.1 with the Blossum 62-12-2 matrix (Corpet, 1988). Black boxes indicate high consensus levels (100%); gray boxes indicate low consensus levels (> 50%).
