Divalent metal ion binding to g1 subunit of myosin and movement of 180 tyrosyl residue.
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.
