Description
Applications: Studies on mechanisms of DNA recombination, replication and repair.
Application for genetic engineering. For dissociation of special structure DNA. Purity: 90% by SDS-PAGE (CBB staining)
E. coli RecQ helicase contributes to the genomic stability as the prototype of RecQ family DNA helicases, mutations of which genes are associated with premature aging and cancer susceptibility, known as Bloom's and Werner's syndromes (1). RecQ helicase functions in both early and late stages of homologous recombination and unwinds DNAs with particular structures, such as the fork structure for replication, the Holliday junction which isanintermediate of recombination, telomere, quadruplex G4-DNA, etc. In replication fork, it Forms a complex with topoisomerase III and regulates DNA topology (1, 2).
The product is over-produced as a recombinant protein and highly purified by several steps of chromatography. Asingle band is observed by SDS-PAGE at 64 kD (Fig 1).
Biochemical Activities: Unwinding duplex DNA, dependent on ATP. DNA-dependent ATPase (Ref.2).
Data Link: UniProtKB/Swiss-Prot P15043 (RECQ_ECOLI)
Storage: Store at -70°C
