The structure of preQ1-III has been reported for Mathews et al. 2015 [2], preQ1-III riboswitch aptamer presents four pairing regions P1-P4, organised as a HL out-type pseudoknot in its structure. preQ1-II presents a bipartite architecture, wich permit a dynamic conformational switch involved in the expression platform accessibility. PreQ1-III riboswitch structure was reported in PDB: 4RZD_A [2] and 6XKN_A and 6XKO_A", "curation": {"author": "Argasinska J, Ontiveros-Palacios N", "seed_source": "Zasha Weinberg, Phillip McCown, Jonathan Liang", "num_seed": 31, "num_full": 10, "num_species": 17, "type": "Cis-reg; riboswitch;", "structure_source": "Published; PMID:25036777"}, "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": 63.0, "trusted": 64.9, "noise": 54.4}}, "release": {"date": "2026-01-16", "number": "15.1"}, "clan": {"acc": null, "id": null}}}
