| Short Name | Rnase_BN |
| description | This entry represents the ribonuclease Z (RNase Z) homologue, RNase BN, from bacteria. RNase BN was considered to be an exonuclease based on its ability to remove the 3'-terminal residue of tRNAs ending in CA, CU, CCU or even CCA []. In E. coli, even though different set of enzymes are used for tRNA 3'-ends processing and RNase Z is thought to be less important than the other ribonucleases. However, E. coli cells lacking the four main enzymes of the exonucleolytic pathway (RNases T, PH, D and II) are viable, whereas further mutation of RNase BN/Z in this genetic context causes an unviable phenotype []. |
