| Description | Thaumatin [ ] is an intensely sweet-tasting protein, 100 000 times sweeter than sucrose on a molar basis [], found in berries from Thaumatococcus daniellii, a tropical flowering plant known as Katemfe. It is induced by attack by viroids, which are single-stranded unencapsulated RNA molecules that do not code for protein.Thaumatin consists of about 200 residues and contains 8 disulphide bonds. Like other PR proteins, thaumatin is predicted to have a mainly beta structure, with a high content of β-turns and little helix []. Several stress-induced proteins of plants have been found to be related to thaumatins:A maize alpha-amylase/trypsin inhibitorTwo tobacco pathogenesis-related proteins: PR-R major and minor forms, which are induced after infection with virusesSalt-induced protein NP24 from tomatoOsmotin, a salt-induced protein from tobacco [ ] Osmotin-like proteins OSML13, OSML15 and OSML81 from potato [ ] P21, a leaf protein from soybeanPWIR2, a leaf protein from wheat [ ] Zeamatin, a maize antifungal protein [ ] This family is also referred to as pathogenesis-related group 5 (PR5), as many thaumatin-like proteins accumulate in plants in response to infection by a pathogen and possess antifungal activity [ ]. The proteins are involved in systemically acquired resistance and stress response in plants, although their precise role is unknown []. The PR5K receptor protein kinase from Arabidopsis comprises an extracellular domain related to the PR5 proteins, and an intracellular protein-serine/threonine kinase domain []. |
