Catalytic role of an arginine residue in the highly conserved and unique sequence of phosphoenolpyruvate carboxylase.

abstract：:The gizzard tropomyosin molecule is composed of two subunits at 1:1 molar ratio. Possible composites of the tropomyosin molecule are two kinds of homodimer (one for each subunit), a heterodimer of two subunits, or a mixture of heterodimer and homodimer(s). We tried to evaluate the native subunit composition of gizzard...
