Efficient DNA ligation in DNA-RNA hybrid helices by Chlorella virus DNA ligase
Single-stranded DNA molecules (ssDNA) annealed to an RNA splint are notoriously poor substrates for DNA ligases. Herein we report the unexpectedly efficient ligation of RNA-splinted DNA by Chlorella virus DNA ligase (PBCV-1 DNA ligase). PBCV-1 DNA ligase ligated ssDNA splinted by RNA with kcat ≈ 8 x 10(-3) s(-1) and K(M) < 1 nM at 25 °C under conditions where T4 DNA ligase produced only 5'-aden...
متن کاملEfficient in situ barcode sequencing using padlock probe-based BaristaSeq
Cellular DNA/RNA tags (barcodes) allow for multiplexed cell lineage tracing and neuronal projection mapping with cellular resolution. Conventional approaches to reading out cellular barcodes trade off spatial resolution with throughput. Bulk sequencing achieves high throughput but sacrifices spatial resolution, whereas manual cell picking has low throughput. In situ sequencing could potentially...

Fidelity of RNA templated end-joining by chlorella virus DNA ligase and a novel iLock assay with improved direct RNA detection accuracy
Ligation-based nucleic acid detection methods are primarily limited to DNA, since they exhibit poor performance on RNA. This is attributed to reduced end-joining efficiency and/or fidelity of ligases. Interestingly, chlorella virus DNA ligase (PBCV-1 DNA ligase) has recently been shown to possess high RNA-templated DNA end-joining activity; however, its fidelity has not yet been systematically ...
