Inactivation of RNase P in Escherichia coli significantly changes post‐transcriptional RNA metabolism

Autor: Sidney R. Kushner, Bijoy K. Mohanty

Publikováno v: Mol Microbiol

Ribonuclease P (RNase P), which is required for the 5'-end maturation of tRNAs in every organism, has been shown to play a limited role in other aspects of RNA metabolism in Escherichia coli. Using RNA-sequencing (RNA-seq), we demonstrate that RNase

Processing of the alaW alaX operon encoding the Ala2 tRNAs in Escherichia coli requires both RNase E and RNase P

Autor: Bijoy K, Mohanty, Sidney R, Kushner

Publikováno v: Molecular microbiologyREFERENCES. 118(6)

The alaW alaX operon encodes the Ala2 tRNAs, one of the two alanine tRNA isotypes in Escherichia coli. Our previous RNA-seq study showed that alaW alaX dicistronic RNA levels increased significantly in the absence of both RNase P and poly(A) polymera

Maturation of the E. coli Glu2, Ile1, and Ala1B tRNAs utilizes a complex processing pathway

Autor: Bijoy K. Mohanty, Keri Nichols, Sidney R. Kushner

Publikováno v: Molecular microbiologyREFERENCES. 118(1-2)

Despite significant progress in understanding the diversity of tRNA processing pathways in Escherichia coli, the mechanism for the maturation of tRNAs encoded within the rRNA operons has not received much attention. Here, we show that the Glu2, Ile1,

Generation of pre-tRNAs from polycistronic operons is the essential function of RNase P in Escherichia coli

Autor: Sidney R. Kushner, Ankit Agrawal, Bijoy K. Mohanty

Publikováno v: Nucleic Acids Research

Ribonuclease P (RNase P) is essential for the 5′-end maturation of tRNAs in all kingdoms of life. In Escherichia coli, temperature sensitive mutations in either its protein (rnpA49) and or RNA (rnpB709) subunits lead to inviability at nonpermissive

The C nucleotide at the mature 5' end of the Escherichia coli proline tRNAs is required for the RNase E cleavage specificity at the 3' terminus as well as functionality

Autor: Bijoy K Mohanty, Valerie Maples, Sidney R Kushner

Publikováno v: Nucleic acids research. 50(3)

Proline tRNA 3′-maturation in Escherichia coli occurs through a one-step RNase E endonucleolytic cleavage immediately after the CCA determinant. This processing pathway is distinct from the 3′-end maturation of the other tRNAs by avoiding the wid

Detailed studies of the Gram-negative model bacterium, Escherichia coli, have demonstrated that post-transcriptional events exert important and possibly greater control over gene regulation than transcription initiation or effective translation. Thus

New Insights into the Relationship between tRNA Processing and Polyadenylation in Escherichia coli

Autor: Sidney R. Kushner, Bijoy K. Mohanty

Publikováno v: Trends Genet

Recent studies suggest that poly(A) polymerase I (PAP I)-mediated polyadenylation in Escherichia coli is highly prevalent among mRNAs as well as tRNA precursors. Primary tRNA transcripts are initially processed endonucleolytically to generate pre-tRN
