noncanonical stereochemical modification [Modified]
Isolated initially from a West Africa plant as a sweet protein (Ming and Hellekant 1994 FEBS Lett 355: 106-108). Chemical modification: There are 4 S-S bonds: C4-C52, C16-C37, C22-C47, and C26-C49 (Kohmura et al. 1996 Biopolymers 38: 553-6). Structure: The protein contains one helix and 3 beta-strands (Nat Struct Biol 1998; 5: 427-31). A refined structure is also available in the PDB.
