The behavior at low-dose exposure (0.033–0.4 kGy) of horseradish peroxidase (HRP) and of two different purified fractions of apple (Jonathan cultivar) peroxidases (named APR1S and APR2S) was studied. The HRP solutions were added with either 0.32 M fructose or glucose in order to study their effect on enzymes activity response under γ (137Cs, dose rate 0.4 kGy/h) irradiation. The obtained results showed similar behavior between HRP-sugar-added solution and apple fraction with higher oligosaccharides content (APR2S) undergoing low-dose treatment. The same pattern was observed between unglycosylated HRP and APR1S with lower oligosaccharides content. These similarities gave us the possibility to conclude that the presence of oligosaccharides, in more or less quantities, influences in the same way the peroxidases activity, from different plant species, exposed to γ irradiation.
