Description |
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 beta-turns and little helix [PMID: 7049841]. Several stress-induced proteins of plants have been found to be related to thaumatins:A maize alpha-amylase/trypsin inhibitor, two tobacco pathogenesis-related proteins: PR-R major and minor forms,which are induced after infection with viruses, Salt-induced protein NP24 from tomato, Osmotin, a salt-induced protein from tobacco [PMID: 16666857], Osmotin-like proteins OSML13, OSML15 and OSML81 from potato [PMID: 7630973], P21, a leaf protein from soybean, PWIR2, a leaf protein from wheat [PMID: 1650615], Zeamatin, a maize antifunal protein [PMID: 7846159]. This protein 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 [PMID: 1463856]. The proteins are involved in systematically acquired resistance and stress response in plants, although their precise role is unknown [PMID: 1463856]. |

Note:
The format for Signature ID is the family name, followed by H or P for HMM or Pattern respectively. The integer suffixed to H or P denotes the length of the sequences used to create the family signature. If no integer is suffixed, it indicates that the signature was created using all the sequences of the family. The integer following the underscore denotes the number of sequences used for the creation of signatures.
For example:
AureinH_21 is a HMM for Aurein family created using 21 sequences.
AureinP16_9 is a pattern for Aurein family derived using 9 input sequences that are 16 residues long. |
