- Py B, Higgins C, Krisch H, Carpousis A. A DEAD-box RNA helicase in the Escherichia coli RNA degradosome. Nature. 1996;381:169-72 pubmed..These results suggest that RhlB acts by unwinding RNA structures that impede the processive activity of PNPase. RhlB is thus an important enzyme in mRNA turnover. ..

Mol Gen Genet. 1997;253:515-9 pubmed..Introduction of a cafA::cat mutation enhanced the temperature sensitivity of the ams1 mutant. These results suggest that there is a functional homology between these two proteins. ..
