Word Map on EC 3.4.23.B14

Reaction

cleavage of hemoglobin. In the S3 and S2 subsites, the plasmepsin 4 orthologs all prefer hydrophobic amino acid residues, Phe or Ile, but reject charged residues such as Lys or Asp. In S2' and S3' subsites these plasmepsins tolerate both hydrophobic and hydrophilic residues =
