Conchiolin, a scleroprotein obtained from the shell of the pearl oyster (Pinctada martensii), was fractionated with 70 per cent acetic acid, 2 N ammonia, the concentrated solution of copper-ethylenediamine, and [Co (py)4] Cl2 in water, respectively. By these treatments, several fractions of conchiolin were obtained.
The N-terminal amino acids of these fractions of conchiolin were proved to be glycine, serine and aspartic acid. The C-terminal amino acids of Conchiolin I-l (70 per cent acetic acid and 2 N ammonia soluble conchiolin) were glycine, serine and threonine.
