چکیده

Background: The C-terminus of pVI activates the adenovirus proteinase. pVI escorts hexon into the nucleus. Results: pVI binds tightly to DNA independent of sequence, Kd = 46 nM. pVI binds tightly to hexon, Kd = 1.1 nM. Conclusion: DNA binding of pVI is first step in the activation of adenovirus proteinase. Significance: Links pVI, hexon, viral DNA and the adenovirus proteinase in virion maturation.

Regulation of a viral proteinase by a peptide and DNA in one-dimensional space: I. binding to DNA AND to hexon of the precursor to protein VI, pVI, of human adenovirus.

The precursor to adenovirus protein VI, pVI, is a multifunctional protein with different roles early and late in virus infection. Here, we focus on two roles late in infection, binding of pVI to DNA and to the major capsid protein hexon. pVI bound to DNA as a monomer independent of DNA sequence with an apparent equilibrium dissociation constant, K(d)((app)), of 46 nm. Bound to double-stranded D...

The adenovirus L4-33K protein regulates both late gene expression patterns and viral DNA packaging.

The adenovirus (Ad) L4-33K protein has been linked to disparate functions during infection. L4-33K is a virus-encoded alternative RNA splicing factor which activates splicing of viral late gene transcripts that contain weak 3' splice sites. Additionally, L4-33K has been indicated to play a role in adenovirus assembly. We generated and characterized an Ad5 L4-33K mutant virus to further explore ...

Isolation and characterization of the DNA and protein binding activities of adenovirus core protein V.

UNLABELLED The structure of adenovirus outer capsid was revealed recently at 3- to 4-Å resolution (V. Reddy, S. Natchiar, P. Stewart, and G. Nemerow, Science 329:1071-1075, 2010, http://dx.doi.org/10.1126/science.1187292); however, precise details on the function and biochemical and structural features for the inner core still are lacking. Protein V is one the most important components of the a...

Rapid purification of HU protein from Halobacillus karajensis

The histone-like protein HU is the most-abundant DNA-binding protein in bacteria. The HU protein non-specifically binds and bends DNA as a hetero- or homodimer, and can participate in DNA supercoiling and DNA condensation. It also takes part in DNA functions such as replication, recombination, and repair. HU does not recognize any specific sequences but shows a certain degree of specificity to ...

The L4 22-kilodalton protein plays a role in packaging of the adenovirus genome.

Packaging of the adenovirus (Ad) genome into a capsid is absolutely dependent upon the presence of a cis-acting region located at the left end of the genome referred to as the packaging domain. The functionally significant sequences within this domain consist of at least seven similar repeats, referred to as the A repeats, which have the consensus sequence 5' TTTG-N(8)-CG 3'. In vitro and in vi...
