CATH Superfamily 2.20.25.10
The name of this superfamily has been modified since the most recent official CATH+ release (v4_3_0). At the point of the last release, this superfamily was: waiting to be named.
FunFam 85: DNA-directed RNA polymerase subunit
Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

DNA binding GO:0003677
Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).

DNA-directed 5'-3' RNA polymerase activity GO:0003899
Catalysis of the reaction: nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1). Utilizes a DNA template, i.e. the catalysis of DNA-template-directed extension of the 3'-end of an RNA strand by one nucleotide at a time. Can initiate a chain 'de novo'.

Transcription initiation from RNA polymerase III promoter GO:0006384
Any process involved in the assembly of the RNA polymerase III preinitiation complex (PIC) at an RNA polymerase III promoter region of a DNA template, resulting in the subsequent synthesis of RNA from that promoter. The initiation phase includes PIC assembly and the formation of the first few bonds in the RNA chain, including abortive initiation, which occurs when the first few nucleotides are repeatedly synthesized and then released. Promoter clearance, or release, is the transition between the initiation and elongation phases of transcription.

TRNA 3'-trailer cleavage GO:0042779
Cleavage of the 3'-end of the pre-tRNA as part of the process of generating the mature 3'-end of the tRNA; may involve endonucleolytic or exonucleolytic cleavage, or both.

TRNA 3'-trailer cleavage GO:0042779
Cleavage of the 3'-end of the pre-tRNA as part of the process of generating the mature 3'-end of the tRNA; may involve endonucleolytic or exonucleolytic cleavage, or both.

Nucleus GO:0005634
A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

RNA polymerase III complex GO:0005666
RNA polymerase III, one of three nuclear DNA-directed RNA polymerases found in all eukaryotes, is a multisubunit complex; typically it produces 5S rRNA, tRNAs and some of the small nuclear RNAs. Two large subunits comprise the most conserved portion including the catalytic site and share similarity with other eukaryotic and bacterial multisubunit RNA polymerases. The remainder of the complex is composed of smaller subunits (generally ten or more), some of which are also found in RNA polymerase I and others of which are also found in RNA polymerases I and II. Although the core is competent to mediate ribonucleic acid synthesis, it requires additional factors to select the appropriate template.

Cytosol GO:0005829
The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
