EXTRACTION OF THAUMATIN FROM THAUMATOCOCCUS DANIELLI: J HIGGINBOTHAM; US PATENT NUMBER 4,011,206 (1976 TO TATE AND LYLE, LTD). CT VERRIPS, EUROPEAN PATENT APPL 54,330 AND 54,331 (BOTH 1982 TO UNILEVER).
COMPRISED OF TWO ELECTROPHORETIC SPECIES, THAUMATINS I AND II, ONE OF WHICH APPEARS TO BE A PARTIALLY DEAMINATED FORM OF THE OTHER. ... THE PROTEIN CONSISTS OF A SINGLE POLYPEPTIDE CHAIN OF 207 RESIDUES; FIVE SETS OF TRIPEPTIDES ARE IDENTICAL WITH TRIPEPTIDES IN MONELLIN.
Thaumatin was one of the sweetening agents studied & found to be low in cariogenic action. No deleterious effect of its use has been found.
Various maturation forms of the plant protein thaumatin were expressed in yeast, using a promoter fragment of the glyceraldehyde-3P-dehydrogenase (GAPDH) gene. Nucleotide sequence analysis of 843 nucleotide GAPDH promoter fragment revealed a characteristic structure with 2 regions of dyad symmetry containing translational starts of GAPDH and a putative 38 amino acid peptide.
