STAXI RNA Motif
The Ssbp, Topoisomerase, Antirestriction, XerDC Integrase RNA motif (STAXI RNA motif) is a conserved RNA-like structure identified using bioinformatics. STAXI RNAs are located near to genes encoding proteins that interact with DNA ( Ssbp, topoisomerase, XerDC integrase) or are associated with such proteins ( antirestriction proteins, which inhibit restriction enzymes). This observation raised the possibility that instances of the STAXI motif function as single-stranded DNA molecules, perhaps during DNA replication or DNA repair. On the other hand, STAXI motifs often contain terminal loops conforming to the stable UNCG tetraloop, but the DNA version of this tetraloop (TNCG) is not especially stable. The STAXI motif consists of a simple pseudoknot structure that is repeated two or more times (see diagram). A number of other RNAs were identified in the same study, including: * Bacteroidales-1 RNA motif * Chlorobi-1 RNA motif * JUMPstart RNA motif * Lactis-plasmid RNA motif *Ocea ...

Enterobacteriales
Enterobacterales is an order of Gram-negative bacteria, Gram-negative, non-spore forming, Facultative anaerobic organism, facultatively anaerobic, rod-shaped bacteria with the class Gammaproteobacteria. The type genus of this order is ''Enterobacter.'' The name Enterobacterales is derived from the Latin term ''Enterobacter'', referring the type genus of the order and the suffix "-ales", an ending used to denote an order. Together, Enterobacterales refers to an order whose nomenclatural type is the genus ''Enterobacter''. Historical Identification and Systematics Enterobacterales was proposed in 2005 under the name "Enterobacteriales". However, the name "Enterobacteriales" was not validated according to the rules of the ''International Code of Nomenclature of Prokaryotes,'' thus it lacked standing in nomenclature, so the name was written in parentheses. "Enterobacteriales" was a monotypic order, containing only the family ''Enterobacteriaceae'', and shared its type genus ''Esch ...
