title: Tropomyosin from adult human skeletal muscle is partially phosphorylated.
abstract: Alpha and beta tropomyosins were isolated from postmortem adult human psoas and pectoralis major muscles. 31P nuclear magnetic resonance and amino acid analysis were used to show that 10% of the major alpha tropomyosin component was phosphorylated. The 31P NMR spectra also suggested that human beta tropomyosin was phosphorylated, but to a lesser extent.
