Functional divergence in the growing family of RNA polymerases.
نویسنده
چکیده
In plants, unorthodox multisubunit RNA polymerases (RNAPs) play key roles in small interfering RNA (siRNA) genesis and function. In a recent issue of Molecular Cell, Ream et al. (2009) established a 12-subunit composition for Arabidopsis RNAPIV and RNAPV. Subunit and sequence divergence between RNAPIV-V and RNAPI-III suggests significant functional deviation of these intriguing RNAPs.

RNA-specific ribonucleotidyl transferases.
RNA-specific nucleotidyl transferases (rNTrs) are a diverse family of template-independent polymerases that add ribonucleotides to the 3'-ends of RNA molecules. All rNTrs share a related active-site architecture first described for DNA polymerase beta and a catalytic mechanism conserved among DNA and RNA polymerases. The best known examples are the nuclear poly(A) polymerases involved in the 3'...
متن کاملAncient RNA stems that terminate transcription
Multi-subunit RNA polymerases are the enzymes that perform transcription in all living organisms and that have emerged before the divergence of domains of life. The structures of catalytic cores and their functions during elongation step of transcription cycle are very similar for all multi-subunit RNA polymerases. In contrast, the mechanisms for terminating the RNA synthesis have seemingly div...
متن کاملNon-canonical DNA transcription enzymes and the conservation of two-barrel RNA polymerases
DNA transcription depends on multimeric RNA polymerases that are exceptionally conserved in all cellular organisms, with an active site region of >500 amino acids mainly harboured by their Rpb1 and Rpb2 subunits. Together with the distantly related eukaryotic RNA-dependent polymerases involved in gene silencing, they form a monophyletic family of ribonucleotide polymerases with a similarly orga...
متن کاملDNA polymerases: structural diversity and common mechanisms.
Possibly the earliest enzymatic activity to appear in evolution was that of the polynucleotide polymerases, the ability to replicate the genome accurately being a prerequisite for evolution itself. Thus, one might anticipate that the mechanism by which all polymerases work would be both simple and universal. Further, these enzymatic scribes must faithfully copy the sequences of the genome into ...
متن کاملA family of poly(U) polymerases.
The GLD-2 family of poly(A) polymerases add successive AMP monomers to the 3' end of specific RNAs, forming a poly(A) tail. Here, we identify a new group of GLD-2-related nucleotidyl transferases from Arabidopsis, Schizosaccharomyces pombe, Caenorhabditis elegans, and humans. Like GLD-2, these enzymes are template independent and add nucleotides to the 3' end of an RNA substrate. However, these...
