Cooperativity of actin-activated ATPase of gizzard heavy meromyosin in the presence of gizzard tropomyosin.
The mechanism for the potentiation of the actin-activated ATPase of smooth muscle myosin by tropomyosin is investigated using smooth muscle actin, tropomyosin, and heavy meromyosin. In the presence of tropomyosin, an increase in Vmax occurs with no effect on KATPase and Kbinding at 20 mM ionic strength. Utilizing N-ethylmaleimide-treated subfragment-1, which forms rigor complexes with actin in ...
متن کاملIsolation of the native form of chicken gizzard myosin light-chain kinase.
A simple and rapid procedure for the purification of the native form of chicken gizzard myosin light-chain kinase (Mr 136000) is described which eliminates problems of proteolysis previously encountered. During this procedure, a calmodulin-binding protein of Mr 141000, which previously co-purified with the myosin light-chain kinase, is removed and shown to be a distinct protein on the basis of ...
متن کاملAdenoviral gizzard erosions in Italian chicken flocks.
TYPE 1 avian adenoviruses belong to the genus Aviadenovirus within the adenovirus family. Five species of fowl adenovirus (fAdV) (designated by the letters A to E) are recognised within the Aviadenovirus genus based largely on molecular criteria, in particular restriction enzyme fragmentation patterns and sequencing data (McFerran and McConnel Adair 2003). fAdV are common infectious agents in p...
متن کاملMolecular properties and functions in vitro of chicken smooth-muscle alpha-actinin in comparison with those of striated-muscle alpha-actinins.
alpha-Actinin purified from chicken gizzard smooth muscle was characterized in comparison with alpha-actinins from chicken striated muscles, or fast-skeletal muscle, slow-skeletal muscle, and cardiac muscle. The gizzard alpha-actinin molecule consisted of two apparently identical subunits with a molecular weight of 100,000 on SDS-polyacrylamide gel electrophoresis, as do striated-muscle alpha-a...
متن کاملStudies on the soluble phosphodiesterases of chicken gizzard smooth muscle.
In this study we describe the identification of four soluble forms of cyclic nucleotide phosphodiesterase from chicken gizzard smooth muscle. These isoenzymes were separated from one another by ion-exchange chromatography on DEAE-cellulose and by calmodulin-Sepharose affinity chromatography. Each form migrates as a single discrete band when it is electrophoresed on non-denaturing polyacrylamide...
