Other claims from this paper (15)
- Observation Leaf catalase activity decreased over development in Phaseolus vulgaris.
- Observation Leaf catalase activity increased over development in Medicago sativa.
- Observation Root nodule catalase remained high and stable in both legumes.
- Mechanism The authors infer that both legumes require high nodule catalase in nitrogen fixing nodules.
- Intervention effect Medicago sativa leaf catalase was relatively sensitive to NaCl in vitro.
- Intervention effect Phaseolus vulgaris nodule catalase was relatively sensitive to NaCl in vitro.
- Mechanism The authors suggest that catalase detoxification of H2O2 is limited under NaCl exposure.
- Intervention effect Nodule catalases were unaffected by oxygen or superoxide radicals.
- Intervention effect Reducing agents strongly inhibited Phaseolus vulgaris nodule catalase.
- Intervention effect Reducing agents partially inhibited Medicago sativa nodule catalase.
- Intervention effect Cyanide was the most potent inhibitor of nodule catalases.
- Observation Purified Phaseolus vulgaris catalase migrated at 42 kDa on SDS-PAGE.
- Observation Purified Medicago sativa catalase migrated at 46 kDa on SDS-PAGE.
- Observation Native Phaseolus vulgaris catalase forms had molecular masses of 59 and 48 kDa.
- Observation Native Medicago sativa catalase forms had molecular masses of 88 and 53 kDa.
