Fig 8. Multiple alignment of the amino-acid sequences of RIPs from the following plant species: the MAP30 from M. charantia, A chain of ricin from R. communis, trichosanthin and karasurin from T. kirilowii, GAP31 from S. multiflora, and curcin 1 from J. curcas performed using CLC Main Workbench 5 software (Qiagen).

Conserved amino acids were found in regions with a high level of identity, particularly in the central region.
