DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Specific peripheric component of RNA polymerase III which synthesizes small RNAs, such as 5S rRNA and tRNAs. The RPC53/RPC4-RPC37/RPC5 subcomplex is required for terminator recognition and reinitiation. Component of the RNA polymerase III (Pol III) complex consisting of 17 subunits. Interacts with RPC53/RPC4. RPC53/RPC4, RPC37/RPC5 and RPC11/RPC10 probably form a Pol III subcomplex. Present with 1590 molecules/cell in log phase SD medium.
