At the molecular level, muscle contraction is defined by myosin molecules pulling actin filaments. New electron cryomicroscopy images with unprecedented resolution taken by researchers at Osaka ...
The standard textbook model of muscle contraction includes only two main players, the filaments actin and myosin, which slide past each other, causing the sarcomere—the basic unit of muscle tissue—to ...
IT was recently reported 1 that the sulphydryl (—SH) agent, parachloromercuribenzoate (PCMB), causes superprecipitation of actomyosin gel. Masking of an —SH group appears to prevent interaction ...
