Total SOD activity and inhibition assays of pollen protein extracts from 16 olive cultivars. a Total SOD activity of pollen protein extracts from 16 olive cultivars. b SOD activity gel after H2O₂ (upper panel) and KCN (lower panel) inhibition assays, respectively. c Type-assignment of the SOD activity bands present in a on the basis of MS-based identification data and their inhibition profiles (b), numbered from I to VII. Bands marked in yellow are considered Mn-SODs as they are not inhibited neither by H₂O₂ nor by KCN. Iron-SODs (red bands) are inhibited by KCN and not by H₂O₂, and Cu,Zn-SODs (blue bands) are inhibited by both H₂O₂ and KCN. 1, ‘Lechín de Sevilla’; 2, ‘Verdial de Vélez Málaga’; 3, ‘Hojiblanca’; 4, ‘Picudo’; 5, ‘Manzanilla de Sevilla’; 6, ‘Arbequina’; 7, ‘Cornicabra’; 8, ‘Blanqueta’; 9, ‘Loaime’; 10, ‘Lucio’; 11, ‘Bella de España’; 12, ‘Empeltre’; 13, ‘Farga’; 14, ‘Frantoio’; 15, ‘Galega’; 16, ‘Picual’
