Structural studies on rabbit skeletal muscle actin. Ordering of the peptides produced by cleavage with cyanogen bromide
W. M. Kuehl, M. A. Conti and R. S. Adelstein
The 17 peptides produced by cleavage of actin with cyanogen bromide have
been ordered with regard to their sequence in the actin molecule. Tryptic
digestion of actin followed by isolation of the methionine-containing
"overlap" peptides permitted the unique alignment of most, but not all of
the cyanogen bromide peptides. However, maleylation of the actin molecule
followed by tryptic digestion and isolation of methionine-containing
peptides from maleylated actin permitted the proper placement of the
remaining cyanogen bromide peptides. The ordering of cyanogen bromide
peptides, together with the amino acid sequence of the individual peptides,
constitutes the entire amino acid sequence of rabbit skeletal muscle actin
