Type 2 subfamily.

RNA polymerase principal sigma factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.

SC2E1.41, rpsB, 30S ribosomal protein S2, len: 310 aa; almost identical to RS2_STRCO 30S ribosomal protein S2 (242 aa), E(): 0, 96.7% identity in 242 aa overlap and also highly similar to many others e.g. RS2_ECOLI 30S ribosomal protein S2 (240 aa), fasta scores; opt: 744 z-score: 950.7 E(): 0, 50.4% identity in 224 aa overlap. Contains PS00962 Ribosomal protein S2 signature 1 and PS00211 ABC transporters family signature (probably a false positive). Also contains Pfam matches to entry S2 PF00318, Ribosomal protein S2, score 304.89 and to entry 60s_ribosomal PF00428, 60s Acidic ribosom [...]

Putative ribonuclease PH; Phosphorolytic 3'-5' exoribonuclease that plays an important role in tRNA 3'-end maturation. Removes nucleotide residues following the 3'-CCA terminus of tRNAs; can also add nucleotides to the ends of RNA molecules by using nucleoside diphosphates as substrates, but this may not be physiologically important. Probably plays a role in initiation of 16S rRNA degradation (leading to ribosome degradation) during starvation.

Conserved hypothetical protein; SCE2.09, unknown, len: 386 aa; weak similarity to several predicted helicases e.g. SW:DNAB_TREPA replicative DNA helicase from Treponema pallidum (438 aa) fasta scores; opt: 188, z-score: 190.6, E(): 0.0027, (36.5% identity in 156 aa overlap) and similar to TR:Q9L1W8 (EMBL:AL138667) Streptomyces coelicolor hypothetical protein SC3D9.11c, 372 aa; fasta scores: opt: 559 Z-score: 528.6 E(): 8.2e-22; 37.466% identity in 363 aa overlap.

Conserved hypothetical protein SC3D9.11c; SC3D9.11c, unknown, len: 372 aa. Weakly similar to Streptomyces coelicolor TR:Q9X8A4 (EMBL:AL049645) hypothetical protein, SCE2.09 (386 aa), fasta scores opt: 559 z-score: 616.2 E(): 6.5e-27; 37.5% identity in 363 aa overlap.

DNA-directed RNA polymerase beta' chain (fragment); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.

Small protein B homologue; Required for rescue of stalled ribosomes mediated by trans- translation. Binds to transfer-messenger RNA (tmRNA), required for stable association of tmRNA with ribosomes. tmRNA and SmpB together mimic tRNA shape, replacing the anticodon stem-loop with SmpB. tmRNA is encoded by the ssrA gene; the 2 termini fold to resemble tRNA(Ala) and it encodes a 'tag peptide', a short internal open reading frame. During trans-translation Ala-aminoacylated tmRNA acts like a tRNA, entering the A-site of stalled ribosomes, displacing the stalled mRNA. The ribosome then switch [...]

SCI35.16c, pheT, proabable phenylalanyl-tRNA synthetase beta chain, len: 840 aa; similar to many e.g. SYFB_ECOLI phenylalanyl-tRNA synthetase beta chain (EC 6.1.1.20) (795 aa), fasta scores; opt: 988 z-score: 1290.9 E(): 0, 36.0% identity in 849 aa overlap. Contains PS00017 ATP/GTP-binding.
