What is Both enolase and the DEAD-box RNA helicase CrhB can form complexes with RNase E in Anabaena sp. PCC 7120 about?

In all domains of life, RNA turnover is important for gene regulation and quality control. The process of RNA metabolism is regulated by many RNA-processing enzymes and assistant proteins, where these proteins usually exist as complexes. However, there is little known about the RNA metabolism, as well as about the RNA degradation complex. In the present study, we described an RNA degradosome-like complex in cyanobacteria and revealed an assembly mechanism different from that of E. coli . Moreover, CrhB could help RNase E in Anabaena sp. strain PCC 7120 degrade double-stranded RNA with a 5′ tail. In addition, CrhB and AnaRne have similar cytoplasm localizations, in contrast to the membrane localization in E. coli .
