Subunits

Subunits Comment Organism
More subunits with molecular weights of 49 kDa and 42 kDa and a subunit with a molecular weight of 45 kDa (which is probably a component of the basal transcription factor of RNA polymerase III, since it is not identified in the mouse enzyme) are modified in the composition of the enzyme isolated from mouse fibroblasts. The two subunits are simultaneously phosphorylated and glycosylated (glycosylation by O-N-acetylglucosamine residues) Mus musculus
More subunits with molecular weights of 60 kDa and 45 kDa and a subunit with a molecular weight of 52 kDa (which is probably one of the basal transcription factors of RNA polymerase III) are modified in the composition of the enzyme isolated from human cells. The three subunits are simultaneously phosphorylated and glycosylated Homo sapiens
