Aar small RNA

In molecular biology, the Aar small RNA is a small RNA (sRNA) produced by species of Acinetobacter. It was first discovered in Acinetobacter baylyi, and is located between the trpS and sucD genes.[1] TrpS encodes tryptophanyl-tRNA-synthetase II and sucD encodes succinyl-coA-synthetase subunit alpha.[2][3] Aar upregulates several mRNAs encoding proteins involved in amino acid metabolism.[4]

In Acinetobacter baumannii, Aar represses expression of the outer membrane protein CarO and the siderophore receptor BfnH : https://academic.oup.com/nar/advance-article/doi/10.1093/nar/gkae668/7734169?login=true
