Ribonuclease E organizes the protein interactions in the Escherichia coli RNA degradosome
Article Abstract:
Ribonuclease E has been shown to organize protein interactions in the Escherichia coli RNA degradosome, which is the prototype of a newly discovered family of multiprotein mechanisms involved in the processing and degradation of RNA. A model for regulation of Rh1B RNA helicase activity has emerged. RNase E appears to be a very complex multidomain protein. The carboxy-terminal half (CTH) of ribonuclease E (RNase E) contains binding sites for the three other major degradosomal parts, enolase, polynucleotide phosphorylase (PNPase) and dead-box RNA helicase Rh1B.

Positive selection systems for discovery of novel polyester biosynthesis genes based on fatty acid detoxification
Article Abstract:
Rhodobacter capsulatus can thrive on short- to long-chain fatty acids as its carbon source. However, negative PhaC strains of Rhodobacter capsulatus failed to thrive on solid media with high levels of certain fatty acids but negative wild-type PhaA and PhaB strains thrived on the same media. This finding indicates that polyhydroxyalkanoates (PHA) detoxify fatty acids on such media and could pave the way for the cloning of PHA biosynthetic enzymes.
