Structures of bacterial polynucleotide kinase in a michaelis complex with nucleoside triphosphate (NTP)-Mg2+ and 5'-OH RNA and a mixed substrate-product complex with NTP-Mg2+ and a 5'-phosphorylated oligonucleotide.
J. Bacteriol. 196(24) , 4285-92, (2014) Clostridium thermocellum polynucleotide kinase (CthPnk), the 5'-end-healing module of a bacterial RNA repair system, catalyzes reversible phosphoryl transfer from a nucleoside triphosphate (NTP) donor to a 5'-OH polynucleotide acceptor, either DNA or RNA. Her... |

Antibodies for fluorescent molecular rotors.
Biochemistry 32 , 7589, (1993) We have prepared monoclonal antibodies for the fluorescent molecular rotors 9-(2-carboxy-2-cyanovinyl)julolidine (CCVJ) and 9-(dicyanovinyl)julolidine (DCVJ). Mouse monoclonal antibody (IgG2b) prepared against CCVJ-conjugated bovine serum albumin strongly bou... |

Colorimetric assay for T4 polynucleotide kinase activity based on the horseradish peroxidase-mimicking DNAzyme combined with λ exonuclease cleavage.
Anal. Chim. Acta 766 , 88-93, (2013) T4 polynucleotide kinase (PNK) plays a critical role in various cellular events. Here, we describe a novel colorimetric strategy for estimating the activity of PNK and screening its inhibitors taking advantage of the efficient cleavage of λ exonuclease and th... |

Fluorogenic substrates with single fluorophores for nucleic acid-modifying enzymes: design principles and new applications.
Anal. Biochem. 424(2) , 142-8, (2012) Nucleic acid-modifying enzymes are widely used in numerous applications. Many of these proteins are also important drug targets. Thus, better assays for the evaluation of their activities are always needed and are continuously being developed. Recently, I rep... |

Signaling mechanisms for muscarinic receptor-mediated coronary vasoconstriction in isolated rat hearts.
J. Pharmacol. Exp. Ther. 293 , 96-106, (2000) Signaling mechanisms for muscarinic receptor-mediated vasoconstriction in coronary resistance arteries were studied in potassium-arrested isolated rat hearts perfused at a constant flow rate. The cholinergic agonist bethanechol was given by bolus injection or... |

Molecular characterization of Plasmodium falciparum putative polynucleotide kinase/phosphatase.
Mol. Biochem. Parasitol. 180(1) , 1-7, (2011) Polynucleotide kinase/phosphatase (PNKP) is a bifunctional enzyme that can phosphorylate the 5'-OH termini and dephosphorylate the 3'-phosphate termini of DNA. It is a DNA repair enzyme involved in the processing of strand break termini, which permits subsequ... |

Dual functions of yeast tRNA ligase in the unfolded protein response: unconventional cytoplasmic splicing of HAC1 pre-mRNA is not sufficient to release translational attenuation.
Mol. Biol. Cell 21(21) , 3722-34, (2010) The unfolded protein response (UPR) is an essential signal transduction to cope with protein-folding stress in the endoplasmic reticulum. In the yeast UPR, the unconventional splicing of HAC1 mRNA is a key step. Translation of HAC1 pre-mRNA (HAC1(u) mRNA) is ... |

Structure and mechanism of the 2',3' phosphatase component of the bacterial Pnkp-Hen1 RNA repair system.
Nucleic Acids Res. 41(11) , 5864-73, (2013) Pnkp is the end-healing and end-sealing component of an RNA repair system present in diverse bacteria from many phyla. Pnkp is composed of three catalytic modules: an N-terminal polynucleotide 5' kinase, a central 2',3' phosphatase and a C-terminal ligase. Th... |

LAS1L interacts with the mammalian Rix1 complex to regulate ribosome biogenesis.
Mol. Biol. Cell 23 , 716-28, (2012) The coordination of RNA polymerase I transcription with pre-rRNA processing, preribosomal particle assembly, and nuclear export is a finely tuned process requiring the concerted actions of a number of accessory factors. However, the exact functions of some of... |

Nol9 is a novel polynucleotide 5'-kinase involved in ribosomal RNA processing.
EMBO J. 29(24) , 4161-71, (2010) In a cell, an enormous amount of energy is channelled into the biogenesis of ribosomal RNAs (rRNAs). In a multistep process involving a large variety of ribosomal and non-ribosomal proteins, mature rRNAs are generated from a long polycistronic precursor. Here... |
