MeSH Heading: Myosin Subfragments
Tree Number(s): D05.750.078.730.475.300; D12.776.210.500.600.300; D12.776.220.525.475.300
Unique ID: D015879
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D015879
Scope Note: Parts of the myosin molecule resulting from cleavage by proteolytic enzymes (PAPAIN; TRYPSIN; or CHYMOTRYPSIN) at well-localized regions. Study of these isolated fragments helps to delineate the functional roles of different parts of myosin. Two of the most common subfragments are myosin S-1 and myosin S-2. S-1 contains the heads of the heavy chains plus the light chains and S-2 contains part of the double-stranded, alpha-helical, heavy chain tail (myosin rod).
