An exodeoxyribonuclease from Streptomyces coelicolor: Expression, purification and biochemical characterization

Biochimica et Biophysica Acta (BBA) - General Subjects, 2007
Streptomyces coelicolor A3(2) produces several intra and extracellular enzymes with deoxyribonuclease activities. The examined N-terminal amino acid sequence of one of extracellular DNAases (TVTSVNVNGLL) and database search on S. coelicolor genome showed a significant homology to the putative secreted exodeoxyribonuclease. The corresponding gene (exoSc)

Association of 3′ → 5′ exodeoxyribonuclease activity with DNA replitase complex from S-phase Chinese hamster embryo fibroblast cells

Experimental Cell Research, 1989
DNA replitase has been described as a complex of enzymes/proteins that are associated with both DNA precursor biosynthesis and DNA replication in mammalian cells [Reddy, G. P. V., and Pardee, A. B. (1980) Proc. Natl. Acad. Sci. USA 77, 3312-3316].

Coupled endo-exodeoxyribonuclease activity from Hela cell nuclei interacts with specific regions of the SV40 mini chromosome

Biochemical and Biophysical Research Communications, 1985
A recently described endo-exodeoxyribonuclease activity (1) was determined to interact preferentially with the origin/enhancer region and the 5' end of the late promoter region of the SV40 mini chromosome. The enzymatic activity has no preferential site of interaction with naked DNA, which suggests, the chromatin organization is responsible for this ...

Coupled endo-exodeoxyribonuclease activity from Hela cell nuclei can function in an excision repair mode in vitro

Biochemical and Biophysical Research Communications, 1985
A single strand specific coupled endo-exodeoxyribonuclease activity has been purified and characterized from the nuclei of HeLa cells(7). The novelity of this activity is in the nature of its associated endo and exonuclease activities. Due to this aspect the ability of this activity to work in unison with DNA polymerase molecules in the process of DNA ...

Plasmodium mitochondrial exodeoxyribonucleases, Exo mit1 and Exo mit2 , are conserved within alveolates with Exo mit1 essential for the establishment of blood‐stage infection

The FEBS Journal
The 6‐kb linear repeat genome of the mitochondrion (mtDNA) of the malaria parasite is among the smallest known in nature, but is well‐conserved in comparison with its apicoplast and nuclear genomes. Except for the presence of base excision repair (BER) and two double‐strand break repair (DSBR) proteins in mitochondria, the ...

12 Exodeoxyribonucleases of Escherichia coli

1981
Publisher Summary Deoxyribonucleases (DNases) catalyze the hydrolysis of phosphodiester bonds in polydeoxyribonucleotides. They are divided into two classes—namely, (1) exonucleases and (2) endonucleases. Essentially, an endonuclease can attack a covalently closed circular strand, but an exonuclease cannot because it requires a chain terminus.
