Not exact matches

The 673 - kilodalton protease complex consists of 14 copies of two different subunits, alpha and beta, forming a barrel - shaped structure of four stacked rings.

Heterotrimeric guanine nucleotide - binding regulatory proteins (G proteins) dissociate into guanosine triphosphate (GTP)- bound alpha subunits and a complex of beta and gamma subunits after interaction with receptors.

(The two alpha subunits may bind either to the proNGF dimer before cleavage or to the complex of the gamma subunit and the NGF dimer after cleavage.)

In 1967 Silvio S. Varon and Eric M. Shooter of the Stanford University School of Medicine isolated NGF by a different procedure and found that the NGF dimer was present as a stable complex with two copies each of two other proteins, which they designated the alpha and gamma subunits.

No one knew if this tail — also known as the C - terminus of the alpha subunit — touches anything else in the core of the RNA polymerase complex.
