The preparation and properties of a group of proteins from the high-sulphur fraction of wool.
A method is reported for the preparation of a group of three proteins from the S-carboxymethylated high-sulphur fraction of wool. These proteins have been partially characterized by their tryptic peptides. All have similar structural features and show an interesting homology within the group and some similarities of sequence with a different group of wool high-sulphur proteins. The evidence for the sequence of some of the peptides is given in a supplementary paper that has been deposited as Supplementary Publication 50008 at the National Lending Library for Science and Technology, Boston Spa, Yorks.
