CC -!- SUBUNIT: Myosin is a hexamer of 2 heavy chains and 4 light chains.
CC -!- PTM: The N-terminus is blocked. N,N,N-trimethylalanine, found in other
CC myosin light chains would not have been detected in the N-terminal
CC tryptic peptide in PubMed:7319048 because it would remain trimethylated
CC and ninhydrin negative after hydrolysis.
CC -!- MISCELLANEOUS: This chain binds calcium.
