additional information | 2fold increase in SO activity in fumigated leaf material as compared to non-fumigated plants | Cytisus scoparius | |
additional information | 4fold increase in sulfite oxidase activity in fumigated leaf material as compared to non-fumigated plants | Quercus ilex | |
additional information | no variation in SO activity between fumigated and non-fumigated plants | Phragmites australis | |
additional information | no variation in SO activity between fumigated and non-fumigated plants | Hedera helix |
Application | Comment | Organism |
---|---|---|
medicine | deficiency in SO, due to either a defect in molybdopterin cofactor biosynthesis or a mutation in the apo-enzyme gene itself, leads to dramatic neurological problems that can cause death in early infancy | Homo sapiens |
additional information | SO may play a role in protecting catalase from sulfite damage. SO may possibly serve as a safety valve to detoxify excess amounts of sulfite and protect the cell from sulfitolysis | Arabidopsis thaliana |

additional information | in tobacco mutants lacking the molybdenum cofactor and, therefore, also lacking active peroxisomal sulfite oxidase, the total sulfite oxidizing capacity of cell extracts decreased to 40% of the wild-type | Nicotiana plumbaginifolia |
