The amino acid sequence of the L-2 light chain of chicken skeletal muscle myosin.

The L-2 light chain of chicken skeletal muscle myosin was isolated and carboxymethylated. The L-2 light chain was digested with trypsin. The tryptic peptides thus obtained were separated and purified. The amino acid compositions and sequences of the tryptic peptides were analyzed. The primary structure of the L-2 light chain of chicken skeletal muscle myosin was determined by comparing the amino acid sequences of these tryptic peptides with the amino acid sequence of the L-2 light chain from rabbit skeletal muscle myosin.
