Structural homology of myosin alkali light chains, troponin C and carp calcium binding protein

Abstract

Sequence comparison between the myosin alkali light chain, troponin C and carp calcium binding protein shows that the pattern of hydrophobic residues which forms the core of calcium binding protein is preserved in both troponin C and myosin alkali light chain. Strong structural similarities between the proteins are suggested. The role of gene duplication in the evolution of troponin C and myosin alkali light chain is discussed.
