Abstract
Changes taking place in actomyosin extracted from Labeo rohita (Rohu) during
storage at -20<'C were studied with a view to find out whether these changes were
denaturation or coagulation of proteins. Changes in solubility, Ca2* ATPase activity
and Mg2* ATPase activity were monitored for a period of 10 weeks. The irreversible
loss of solubility and Caz* and Mg2* ATPase activities indicate that an irreversible
aggregation of proteins, probably through covalent disulphide bonds is taking place
during frozen storage of rohu actomyosin and this is suggestive of protein
coagulation, as distinct from protein denaturation.
