Evidence that unphosphorylated smooth muscle myosin supports smooth muscle contraction.

E Grazi1, G Trombetta.   

Abstract

Unphosphorylated smooth muscle myosin filaments do not disassemble in MgATP, provided that the solution is supplemented either by 25% serum albumin or by 6% polyethylene glycol 6000. These filaments are able to support actomyosin retraction but their ATPase activity is not activated by tropomyosin-decorated F-actin.
