malfunction | although the rate of H2O2 decomposition is about 30times lower in the katG deletion mutant than in the wild type, the strain has a normal phenotype and its doubling time as well as its resistance to H2O2 and methyl viologen are indistinguishable from those of the wild type | Synechocystis sp. |
physiological function | catalase-peroxidase has a protective role against environmental H2O2 | Synechocystis sp. |
