Label Id Description
plastid-encoded plastid RNA polymerase complex B GO_0000344 [A plastid-encoded DNA-directed RNA polymerase complex that resembles eubacterial multisubunit RNA polymerases with a core composed of alpha, beta, and beta-prime subunits. An additional subunit, a sigma factor, is required for promoter recognition. PEP-B is distinguished from PEP-A by its sensitivity to the antibiotic rifampicin. PEP-B is found in both etioplasts and chloroplasts, but is the predominate form in etioplasts. It forms the core of the PEP-A form; the conversion from PEP-B to PEP-A occurs during chloroplast maturation.]
plastid-encoded plastid RNA polymerase complex GO_0000427 [An RNA polymerase complex containing polypeptides encoded by the plastid genome. Plastid-encoded DNA-directed RNA polymerases resemble eubacterial multisubunit RNA polymerases, with a core composed of alpha, beta, and beta-prime subunits. Some forms contain multiple additional subunits. An additional sigma factor subunit is required for promoter recognition.]
cytosolic DNA-directed RNA polymerase complex GO_0000345 [The eubacterial DNA-directed RNA polymerase is a multisubunit complex with a core composed of the essential subunits beta-prime, beta, and two copies of alpha and a fifth nonessential subunit called omega. An additional subunit, a sigma factor, is required for promoter recognition and specificity.]
RNA cap 4 binding GO_0000342 [Binding to a hypermethylated cap structure consisting of 7-methylguanosine (m(7)G) followed by four methylated nucleotides (cap 4): 7-methylguanosine-ppp-N6, N6, 2'-O-trimethyladenosine-p-2'-O-methyladenosine-p-2'-O-methylcytosine-p-N3, 2'-O-dimethyluridine Such caps are known to be found at the 5' ends of SL RNAs of trypanosomatid protozoa.]
RNA cap binding GO_0000339 [Binding to a 7-methylguanosine (m7G) group or derivative located at the 5' end of an RNA molecule.]
plastid-encoded plastid RNA polymerase complex A GO_0000343 [A plastid-encoded DNA-directed RNA polymerase complex that resembles eubacterial multisubunit RNA polymerases, with a core composed of alpha, beta, and beta-prime subunits. An additional subunit, a sigma factor, is required for promoter recognition. PEP-A is generated from the PEP-B form during chloroplast maturation to generate a complex composed of at least thirteen polypeptides that is not sensitive to the antibiotic rifampicin, like its precursor form the PEP-B complex.]
RNA 7-methylguanosine cap binding GO_0000340 [Binding to a 7-methylguanosine group added cotranscriptionally to the 5' end of RNA molecules transcribed by polymerase II.]
RNA trimethylguanosine cap binding GO_0000341 [Binding to the trimethylguanosine (m(3)(2,2,7)-GTP) group located at the 5' end of some RNA molecules. Such trimethylated cap structures, generally produced by posttranscriptional modification of a 7-methylguanosine cap, are often found on snRNAs and snoRNAs transcribed by RNA polymerase II, but have also be found on snRNAs transcribed by RNA polymerase III. They have also been found on a subset of the mRNA population in some species, e.g. C. elegans.]
endonucleolytic cleavage between LSU-rRNA and 5S rRNA of tricistronic rRNA transcript (SSU-rRNA, LSU-rRNA, 5S) GO_0000458 [Endonucleolytic cleavage to separate a pre-LSU-rRNA from a pre-5S rRNA originally produced as a tricistronic rRNA transcript that contains the Small Subunit (SSU) rRNA, the Large Subunit (LSU) rRNA, and the 5S rRNA, in that order, from 5' to 3' along the primary transcript. Note that the use of the word tricistronic refers only to the number of mature rRNA molecules which will be produced from the primary transcript and ignores tRNAs that may also be present within the primary transcript.]
endonucleolytic cleavage of tricistronic rRNA transcript (SSU-rRNA, LSU-rRNA, 5S) GO_0000449 [Endonucleolytic cleavage of a pre-rRNA molecule originally produced as a tricistronic rRNA transcript that contains the Small Subunit (SSU) rRNA, the Large Subunit (LSU) rRNA, and the 5S rRNA, in that order, from 5' to 3' along the primary transcript. For example, primary ribosomal RNA transcripts containing three genes, in this order, are produced in E. coli and other prokaryotic species. Note that the use of the word tricistronic refers only to the number of mature rRNA molecules which will be produced from the primary transcript and ignores tRNAs that may also be present within the primary transcript.]
obsolete exonucleolytic trimming involved in rRNA processing GO_0000459 [OBSOLETE. Exonucleolytic digestion of a pre-rRNA molecule in the process to generate a mature rRNA molecule.]
obsolete dimethylation involved in SSU-rRNA maturation GO_0000456 [OBSOLETE. Dimethylation of the N6 amino groups of two consecutive adenosine residues near the 3'-end of the SSU rRNA. This process has been conserved from bacteria to eukaryotes.]
endonucleolytic cleavage between SSU-rRNA and LSU-rRNA of tricistronic rRNA transcript (SSU-rRNA, LSU-rRNA, 5S) GO_0000457 [Endonucleolytic cleavage to separate a pre-SSU-rRNA from a pre-LSU-rRNA originally produced as a tricistronic rRNA transcript that contains the Small Subunit (SSU) rRNA, the Large Subunit (LSU) rRNA, and the 5S rRNA, in that order, from 5' to 3' along the primary transcript. Note that the use of the word tricistronic refers only to the number of mature rRNA molecules which will be produced from the primary transcript and ignores tRNAs that may also be present within the primary transcript.]

rRNA pseudouridine synthesis GO_0031118 [The intramolecular conversion of uridine to pseudouridine in an rRNA molecule.]
enzyme-directed rRNA pseudouridine synthesis GO_0000455 [The intramolecular conversion of uridine to pseudouridine during ribosome biogenesis where the enzyme specifies the site that becomes pseudouridylated without using a guide RNA.]
snoRNA guided rRNA 2'-O-methylation GO_0000452 [The posttranscriptional addition of methyl groups to the 2'-oxygen atom of nucleotide residues in an rRNA molecule during ribosome biogenesis using a snoRNA guide that targets the position of methylation.]

Primary ribosomal RNA transcripts with two genes in this order are produced in Archaeal species.]
