1. Crude extracts of the extreme halophile @entity28887 contain separable DNA-dependent and RNA-dependent RNA polymerases. 2. The RNA-dependent enzyme has been purified about 2800-fold. 3. It requires RNA, preferably of high molecular weight, and all four @entity8660 to incorporate @entity3209 -labelled @entity9953 into an acid-insoluble, ribonuclease-sensitive product. 4. Both the stability and activity of the RNA polymerase are relatively insensitive to changes in @entity4337 or @entity2827 concentration, but incorporation is stimulated by both @entity1025 and @entity3281 . 5. The molecular weight of the enzyme is about 17000-18000.
