Recognition of DNA substrates by T4 bacteriophage polynucleotide kinase.

T4 phage polynucleotide kinase (PNK) displays 5'-hydroxyl kinase, 3'-phosphatase and 2',3'-cyclic phosphodiesterase activities. The enzyme phosphorylates the 5' hydroxyl termini of a wide variety of nucleic acid substrates, a behavior studied here through the determination of a series of crystal structures with single-stranded (ss)DNA oligonucleotide substrates of various lengths and sequences....

Mechanism for priming DNA synthesis by yeast DNA Polymerase α

The DNA Polymerase α (Pol α)/primase complex initiates DNA synthesis in eukaryotic replication. In the complex, Pol α and primase cooperate in the production of RNA-DNA oligonucleotides that prime synthesis of new DNA. Here we report crystal structures of the catalytic core of yeast Pol α in unliganded form, bound to an RNA primer/DNA template and extending an RNA primer with deoxynucleotides. ...

DNA photodamage recognition by RNA polymerase II.

During gene transcription, RNA polymerase (Pol) II encounters obstacles, including lesions in the DNA template. Here, we review a recent structure-function analysis of Pol II transcribing DNA with a bulky photo-lesion in the template strand. The study provided the molecular basis for recognition of a damaged DNA by Pol II, which is the first step in transcription-coupled DNA repair (TCR). The r...

SPECIFIC AMPLIFICATION OF ASPERGILLUS FUMlGATUS DNA BY POLYMERASE CHAIN REACTION

Invasive aspergillosis (1 is a life-threatening condition in immunocompromised patients. An early diagnosis is of great importance because early treatment may resolve this potentially fatal infection. Recently, the polymerase chain reaction (PCR) has been used successfully in detecting specific DNA of several pathogen. In this study, nested PCR was used to detect DNA specific for A!.pergiflus s...
