{"rfam": {"acc": "RF00444", "id": "PrrF", "description": "PrrF RNA", "comment": "PrrF RNA is a small RNA involved in iron homeostasis and is found exclusively in Pseudomonas species. PrrF sequences are the functional homologues of Rfam:RF00057 and are found in tandem. Their expression is induced under iron limitation by the ferric uptake regulator (Fur) and they act to negatively regulate several genes including sodB and sdh. Both homologues inhibit translation of antR mRNA, which affects quorum sensing and virulence factor production.[2]", "curation": {"author": "Moxon SJ", "seed_source": "PMID:15210934", "num_seed": 18, "num_full": 107, "num_species": 85, "type": "Gene; sRNA;", "structure_source": "Published; PMID:15210934"}, "cm": {"build_command": "cmbuild -F CM SEED", "calibrate_command": "cmcalibrate --mpi CM", "search_command": "cmsearch --cpu 4 --verbose --nohmmonly -T 30.00 -Z 2958934 CM SEQDB", "cutoffs": {"gathering": 90.0, "trusted": 92.4, "noise": 87.8}}, "release": {"date": "2026-01-16", "number": "15.1"}, "clan": {"acc": null, "id": null}}}
