Sequences of amino acid residues in silk fibroin.
An outstanding problem in protein chemistry is the determination of the arrangement or sequence of amino acid residues in the peptide chains. One approach to the partial solution of this problem is through a study of the smaller degradation products present in partial hydrolysates of proteins, preferably those produced on treatment with acid (1). This method is especially attractive when the pr...
متن کاملCorrelation between fibroin amino acid sequence and physical silk properties.
The fiber properties of lepidopteran silk depend on the amino acid repeats that interact during H-fibroin polymerization. The aim of our research was to relate repeat composition to insect biology and fiber strength. Representative regions of the H-fibroin genes were sequenced and analyzed in three pyralid species: wax moth (Galleria mellonella), European flour moth (Ephestia kuehniella), and I...
متن کاملAmino acid sequences involving the histidine residues of porcine trypsin.
is identical with that found in the region of the active center of bovine trypsin, which includes histidine-29 and histidine-46, except that a serine residue (asterisk) replaces a tyrosine residue in the bovine enzyme. The sequence of one of the two other histidine-containing peptides bears some similarity to the sequence surrounding histidine-79 of bovine trypsin. The lack of structural homolo...
متن کاملSome amino acid sequences in the amorphous fraction of the fibroin of Bombyx mori.
When an aqueous solution of the fibroin of Bombyx mori is treated with chymotrypsin, a white precipitate is formed that contains approximately 60% of the nitrogen of the original fibroin, and the remaining 40% of the nitrogen remains in solution in the form of a mixture of water-soluble peptides. These two fractions, the precipitate and the mixture of soluble peptides, we propose to call fracti...
متن کاملNonmulberry Silk Fibroin Scaffold Shows Superior Osteoconductivity Than Mulberry Silk Fibroin in Calvarial Bone Regeneration.
Recent years have witnessed the advancement of silk biomaterials in bone tissue engineering, although clinical application of the same is still in its infancy. In this study, the potential of pure nonmulberry Antheraea mylitta (Am) fibroin scaffold, without preloading with bone precursor cells, to repair calvarial bone defect in a rat model is explored and compared with its mulberry counterpart...
