The silver salt cleavage of the Cytochrome C Horse Heart (CCHH) protein stu
died with API lead to identification of the deheminised parent protein, the
heme fraction and two small peptides corresponding to cleavage at aminoaci
d 65. The API spectrum nm in D2O/CH3OD showed 196 hydrogen exchange for CCH
H and 188 hydrogen exchange for H2O/CH3OH.
