EcCI N-terminal sequences in comparison with other inhibitors. (A) Alignment of the EcCI A chain; (B) alignment of the EcCI B chain with BbCI, cysteine proteinase inhibitor from B. bahinioides [37], LlTI, L. leucocephala trypsin inhibitor [51]; Pj from P. juliflora [34]; ApTI, A. pavonina trypsin inhibitor [35]; EcTI, E. contortisiliquum trypsin inhibitor [7,10]; and AcTI, A. confuse trypsin inhibitor [52]; Dashes indicate gaps that were introduced for optimal alignment and maximum similarity in the MULTALIN program. Residues identical to EcCI are displayed in black boxes.
