The analysis of hemoglobin digestion products by both gradient SDS-PAGE and Bio-Gel P2 chromatography, the inhibition of protease activity by E-64, leupeptin, iodoacetate, and p-hydroxymercuribenzoate, and N-terminal amino acid sequence analysis all indicate that EP-B is a cysteine proteinase.

Carboxypeptidase and protease activities of hormone-treated barley (Hordeum vulgare cv Himalaya) aleurone layers were investigated using the substrates N-carbobenzoxy-Ala-Phe and hemoglobin.
A differential effect of gibberellic acid (GA (3)) on these activities was observed.

This protease constitutes a major portion of the protease activity secreted from half-seeds between 72 to 96 hours of incubation in the presence of GA (3) as detected on activity gels containing hemoglobin as the substrate.
