Observed versus Random Frequencies of Backbone Cleavages Adjacent to Acidic (Asp and Glu), Basic (Arg, Lys, and His), and Proline Residues for All Charge States of the Proteins Dissociated by SORI-CAD in This Work^a

		acidic %	basic %	proline %
cytochrome c	observed	30	45	7
	random	20	39	8
myoglobin	observed	38	36	6
	random	27	36	5
carbonic anhydrase	observed	15	10	33
	random	20	25	14

^aA total of 44, 47, and 39 backbone cleavages are observed for cytochrome c, myoglobin, and carbonic anhydrase, respectively.
