S. Futaki et al., PSEUDO-SYMMETRICAL PROTEIN - CONSTRUCTION OF A 4-HELIX-BUNDLE PROTEINWITH 4 INTRAMOLECULAR DISULFIDE CROSS-LINKINGS, Tetrahedron letters, 37(2), 1996, pp. 201-204
An 84-residue cyclic protein, which has a four-helix-bundle structure,
was constructed by assembling four helical peptides with four intramo
lecular disulfide cross-linkings.
