CC -!- SUBCELLULAR LOCATION: Vacuole.
CC -!- MISCELLANEOUS: PR proteins are acid-soluble, protease-resistant
CC proteins which accumulate in the intercellular spaces of many plants as
CC a result of the hypersensitive reaction to a pathogen.
CC -!- MISCELLANEOUS: PR-R exists as two isoforms in tobacco, a major and a
CC minor form.
CC -!- SIMILARITY: Belongs to the thaumatin family. {ECO:0000255|PROSITE-
CC ProRule:PRU00699}.
