Structure-function relationships of the adenovirus DNA-binding protein.
The M, = 72,000 adenovirus-coded DNA-binding protein is required for viral DNA replication and is involved in virus transcription and transformation. This protein, as isolated from infected cells, is a phosphoprotein with extensive charge heterogeneity. Between 9 and 11 distinct charged species of this protein were detected by isoelectric focusing. Treatment of the protein with alkaline phospha...
متن کاملBiochemical analysis of adenovirus type 5 DNA-binding protein mutants.
We previously reported the isolation and functional characterization of seven adenovirus type 5 (Ad5) DNA-binding protein (DBP) point mutants (Quinn, C. O., and Kitchingman, G. R. (1986) J. Virol. 60, 653-661). Six of the seven mutants were defective in their ability to help adeno-associated virus replicate its DNA. To determine the level at which the mutations affect this function of the DBP, ...
متن کاملAdenovirus type 5 DNA binding protein stimulates binding of DNA polymerase to the replication origin.
The adenovirus (Ad) DNA-binding protein (DBP) is essential for the elongation phase of Ad DNA replication by unwinding the template in an ATP-independent fashion, employing its capacity to form multimers. DBP also enhances the rate of initiation, with the highest levels obtained at low concentrations of Ad DNA polymerase (Pol). Here, we show that stimulation of initiation depends on the templat...
متن کاملAdenovirus DNA replication: protein priming, jumping back and the role of the DNA binding protein DBP.
The adenovirus (Ad) genome is a linear double-stranded (ds) molecule containing about 36 kilobase pairs. At each end of the genome an approximately 100 base pair (bp) inverted terminal repeat (ITR) is found, the exact length depending on the serotype. To the 5'-end of each ITR, a 55-kDa terminal protein (TP) is covalently coupled. The Ad DNA replication system was one of the first replication s...
متن کاملFilter-binding assay for covalent DNA-protein complexes: adenovirus DNA-terminal protein complex.
A rapid, simple, and quantitative filter-binding assay using glass fiber filters has been developed to detect the convalent adenovirus DNA-terminal protein complex. The assay is unusually sensitive because binding of protein-free DNA generally is less than 0.1%. Binding of the adenovirus complex to filters is mediated by terminal protein. We have found that: (i) the adenovirus complex binds max...
