Cadystin A and B, major unit peptides comprising cadmium binding peptides induced in a fission yeast―separation, revision of structures and synthesis

Abstract The unit peptide, cadystin, of the cadmium-binding peptides occurring in a fission yeast was further separated into two major components, cadystin A and B, structures of which were determined to be 1 and 2, respectively, and confirmed by synthesis. The structure previously reported for cadystin was thus revised.

Structure of cadystin, the unit-peptide of cadmium-binding peptides induced in a fission yeast, schizosaccharomyces pombe

Abstract The unit-peptide, cadystin, of cadmium-binding peptides occurring in a fission yeast, S. pombe was determined to have structure H-γ-Glu-Cys-γ-Glu-Cys-Cys-γ-glu-Gly-OH; all Glu and two cys being L-form, whereas one of the Cyss D-form.
