Thermodynamic study of interaction between phthalocyanines with calf thymus DNA
The experimental determination of formation constant for interaction of two water soluble phthalocyanines,Cobalt (II) 4,4',4",4'"-tetrasulpho phthalocyanine (CoTsPc ) and Manganese(II) 4,4',4",4"-tetrasulphophthalocyanine (MnTsPc ) , with calf thymus DNA have been studied by UV-Vis spectrophotometric methodat lrnM phosphate buffer , pH 7.4 and at 5 different temperatures 20,25,30,35 and 400CC ....
متن کاملFour different DNA helicases from calf thymus.
Using a strand displacement assay we have followed DNA helicase activities during the simultaneous isolation of several enzymes from calf thymus such as DNA polymerases alpha, delta, and epsilon, proliferating cell nuclear antigen, and replication factor A. Thus we were able to discriminate and isolate four different DNA helicases called A, B, C, and D. DNA helicase A is identical with the enzy...
متن کاملDNA polymerase lambda from calf thymus preferentially replicates damaged DNA.
A new gene (POLL), has been identified encoding the novel DNA polymerase lambda and mapped to mouse chromosome 19 and at human chromosome 10. DNA polymerase lambda contains all the critical residues involved in DNA binding, nucleotide binding, nucleotide selection, and catalysis of DNA polymerization and has been assigned to family X based on sequence homology with polymerase beta, lambda, mu, ...
متن کاملFurther studies on partially purified calf thymus DNA polymerase a.
Attempts to prevent the urea conversion of a 200-230,000 molecular weight DNA polymerase alpha to a 150-170,000 molecular weight form by the inclusion of protease inhibitors have not been successful. No other method has been found capable of dissociating a 50-70,000 fragment or subunit from the DNA polymerase subunit. Addition of this 50-70,000 subunit to the polymerase subunit does not aid the...
متن کاملRheology of Semi-dilute Solutions of Calf-thymus DNA
We study the rheology of semi-dilute solutions of the sodium salt of calf-thymus DNA in the linear and nonlinear regimes. The frequency response data can be fitted very well to the hybrid model with two dominant relaxation times τ0 and τ1. The ratio (τ0=τ1) 5 is seen to be fairly constant on changing the temperature from 20 to 30C. The shear rate dependence of viscosity can be fitted to the Car...
