title: Divalent metal ion binding to g1 subunit of myosin and movement of 180 tyrosyl residue.
abstract: Binding of divalent metal ions to the g1 subunit isolated from myosin was shown by the difference UV-absorption spectrum. The difference spectrum indicated movement of a tyrosyl residue of g1. The residue responsible for the difference spectrum was assigned to be 180 Tyr.
