In contrast to DNA-related research, RNA-related research is limited by the availability of synthetic sequences. Recent improvements in chem. synthesis allow Xeragon AG to offer custom RNA sequences - up to 100mers - in high quantity and quality at an affo ...
Telomerase is the ribonucleoprotein enzyme responsible for the replication of chromosome ends in most eukaryotes. In the ciliate Euplotes aediculatus, the protein p43 biochemically co-purifies with active telomerase and appears to be stoichiometric with bo ...
The reaction of d,l-5'-activated nucleotide of adenosine in the presence and absence of montmorillonite gave 60:40 and 96:4 ratios, resp. of the d,d- and l,l:d,l- and l,d-dimers. [on SciFinder (R)] ...
In this chapter, we have focused on the biochemistry of IRP-1 and the features which distinguish it from the related RNA-binding protein, IRP-2. IRP-1 is the cytoplasmic isoform of the enzyme aconitase, and, depending on iron status, may switch between enz ...
Replication (single-turnover) of pyranosyl-RNA (p-RNA) sequences can be accomplished reliably by template-directed ligation of 2',3'-cyclophosphates of short oligomers. The ligation process was studied using (mostly) octamers as templates and tetramers as ...
The authors evaluated the RNA binding of all eight possible stereoisomers of LNA. Synthesis of "a-l-xylo-LNA" has been accomplished and the remaining four stereoisomers, all enantiomers of the four synthesized diastereoisomers, are indirectly evaluated b ...
The soln. structure of the duplex formed by self-pairing of the p-RNA octamer b-D-ribopyranosyl-(2'->4')-(CGAATTCG) was studied by NMR techniques and, independently, by mol.-dynamics calcns. The resonances of all non-exchanging protons, H-bearing C-atoms, ...
Primary transcripts in eukaryotic cells undergo several processing steps within the nucleus, and resulting mature RNA molecules are selectively exported to the cytoplasm. Nucleo-cytoplasmic mRNA transport is an active process that likely involves RNA-prote ...
We describe a new procedure to identify RNA or DNA binding sites in proteins, based on a combination of UV cross-linking and single-hit chemical peptide cleavage. Site-directed mutagenesis is used to create a series of mutants with single Asn-Gly sequences ...
