| Addtional Information | FUNCTION:May interact with bacterial adhesins thereby protecting the reproductive tissues from microbial attack. Has no oxalate oxidase activity.CATALYTIC ACTIVITY:2 superoxide 2 H() = O(2) H(2)O(2).COFACTOR:Binds 1 manganese ion per monomer.SUBUNIT:Monomer. In the absence of manganese, it forms tetrameric and pentameric forms which show superoxide dismutase activity.Note=Found in the nectar.TISSUE SPECIFICITY:Nectary tissues and to a lower level ovary.Not detected in petals, stems, leaves, roots or other floral tissues.DEVELOPMENTAL STAGE:Expressed during nectar secretion, while the flowers remain open.MASS SPECTROMETRY:Mass=22533; Mass_error=58; Method=MALDI; Range=33-229; Source=PubMed:10952990;SIMILARITY:Belongs to the germin family. |
