(Submitter supplied) Endonucleolytic cleavage within polycistronic mRNAs can lead to differential stability and discordant abundance among co-transcribed genes. RNase Y, the major endonuclease for mRNA decay in Bacillus subtilis, was originally identified for its cleavage activity towards the cggR-gapA operon, an event that differentiates the expression of a glycolytic enzyme from its transcriptional regulator. A three-protein Y-complex (YlbF, YmcA, and YaaT) was recently identified that is also required for this cleavage in vivo, raising the possibility that it is an accessory factor acting to regulate RNase Y.
