The RNA ligase RtcB reverses MazF-induced ribosome heterogeneity in Escherichia coli. [PDF]
When Escherichia coli encounters stress, the endoribonuclease MazF initiates a post-transcriptional response that results in the reprogramming of protein synthesis.

Elimination of ligation dependent artifacts in T4 RNA ligase to achieve high efficiency and low bias microRNA capture. [PDF]
Adapter ligation is a critical first step in many microRNA analysis methods including microarray, qPCR, and sequencing. Previous studies have shown that ligation bias can have dramatic effects on both the fidelity of expression profiles and ...

Purification of Histidine-Tagged T4 RNA Ligase from E. coli [PDF]
Here we report the construction of a histidine-tagged T4 RNA ligase expression plasmid (pRHT4). The construct, when overexpressed in BL21 (DE3) cells, allows the preparation of large quantities of T4 RNA ligase in high purity using only a single ...

Coevolution of RtcB and Archease created a multiple-turnover RNA ligase. [PDF]
RtcB is a noncanonical RNA ligase that joins either 2′,3′-cyclic phosphate or 3′-phosphate termini to 5′-hydroxyl termini. The genes encoding RtcB and Archease constitute a tRNA splicing operon in many organisms.

Structure and two-metal mechanism of a eukaryal nick-sealing RNA ligase. [PDF]
Significance Polynucleotide ligases are an ancient superfamily of nucleic acid repair enzymes that join 3′-OH and 5′-PO4 DNA or RNA ends. Ligases react with ATP or NAD+ to form a covalent enzyme–adenylate intermediate in which AMP is linked via a P–N ...

Adenylylation of small RNA sequencing adapters using the TS2126 RNA ligase I. [PDF]
Many high-throughput small RNA next-generation sequencing protocols use 5′ preadenylylated DNA oligonucleotide adapters during cDNA library preparation. Preadenylylation of the DNA adapter's 5′ end frees from ATP-dependence the ligation of the adapter to

Genetic and Functional Analyses of Archaeal ATP-Dependent RNA Ligase in C/D Box sRNA Circularization and Ribosomal RNA Processing [PDF]
RNA ligases play important roles in repairing and circularizing RNAs post-transcriptionally. In this study, we generated an allelic knockout of ATP-dependent RNA ligase (Rnl) in the hyperthermophilic archaeon Thermococcus kodakarensis to identify its ...

T4 RNA Ligase 2 truncated active site mutants: improved tools for RNA analysis
Background T4 RNA ligases 1 and 2 are useful tools for RNA analysis. Their use upstream of RNA analyses such as high-throughput RNA sequencing and microarrays has recently increased their importance.
