Additional file 1: of New perspectives on the plant PARP family: Arabidopsis PARP3 is inactive, and PARP1 exhibits predominant poly (ADP-ribose) polymerase activity in response to DNA damage

Figure S1 Domain architecture and sequence analysis of PARP members in Arabidopsis and humans. (A) Comparison of the domain architecture between human and Arabidopsis PARP1, PARP2 and PARP3. (B) Motif-based sequence alignment of the PARP signature of Arabidopsis PARP1, PARP2 and PARP3. Stars show the conserved H-Y-E triad in AtPARP1 and AtPARP2, which has an alternate form in AtPARP3. Red frames show the sequence motifs 1, 2 and 3. The letters with the same color represent conserved amino acids. (PDF 10681 kb)
