Multiple sequence alignment of the Albizia procera amino acid sequence with Carica papaya, Hordeum vulgare and Cajanus cajan. The signal peptide comprises eighteen amino acids marked by yellow bars, while the pro-peptide peptide ranges between 19 and 134 (red bars). Three intra-strand disulfide linkages are indicated by yellow circles and corresponding numbers. Catalytic residues (Gln, His and Asp) are conserved and indicated by a red background.
