Description
Description
DNA-directed RNA polymerases (RNAPs) catalyze the synthesis of RNA from DNA templates. Nuclear DNA is transcribed by three different multi-subunit polymerases, RNAPs I, II and III, which synthesize mRNAs, rRNAs, tRNAs and other non-coding RNAs. Although composed of between 12-17 subunits, all three nuclear RNAPs contain a ten-subunit catalytic core. Mitochondrial RNA is synthesized by a single subunit RNA polymerase. DNA primases are a class of RNA polymerases that catalyse the synthesis of short RNA primers that are extended by DNA polymerases during DNA replication. (Adapted from PMID:22365827 and PMID:19540940.)
Notes on Group

The 'RNA polymerase catalytic subunits' group contains the core RNAP subunits defined in PMID:22365827, together with the DNA primase catalytic subunit and the single subunit mitochondrial RNAP.
