Fig. 2 Amino acid sequence alignment of PEPCs AtPEPC1, AtPEPC2, AtPEPC3: Arabidopsis thaliana AtPEPC1, AtPEPC2, AtPEPC3; SbPEPC1, SbPEPC2, SbPEPC3: Sorghum bicolor SbPEPC1, SbPEPC2, SbPEPC3; GmPEPC: Glycine max GmPEPC; ZmPEPC1, ZmPEPC2: Zea mays ZmPEPC1, 2; StPEPC: Solanum tuberosum StPEPC; AhPEPC: Arachis hypogaea AhPEPC; RcPEPC: Ricinus communis RcPEPC; NtPEPC: Nicotiana tabacum NtPEPC. The corresponding GenBank protein numbers are Q9MAH0.1, Q5GM68.2, Q84VW9.2, P29195.1, P29194.1, P15804.2, P51061.1, P04711.2, P51059.1, P29196.2, ABY87944.1, ABR29878.1, and P27154.1, respectively. The amino acids with an entire homology are shown by a black background, and those shared non-identical conserved identity by a graybackground (≥ 60% similarity).
