Simian virus 40 integration site in an adenovirus 7-simian virus 40 hybrid DNA molecule.
The E46(+) strain of Adenovirus 7 is a mixed-virus population containing defective Adenoviurs 7-SV40 hybrid particles and helper, nonhybrid Adenovirus 7 particles. We have applied electron microscopic mapping techniques to obtain a physical map of the genome of the hybrid particles present in E46(+)PL1, a substrain of E46(+) derived from a single two-hit plaque. DNA molecules extracted from pur...
متن کاملDensity differences between hybrid and nonhybrid particles in two adenovirus-simian virus 40 hybrid populations.
The adenovirus 7-simian virus 40 hybrid virus population E46(+) was subjected to fixed-angle equilibrium density gradient centrifugation in CsCl. A difference in buoyant density between the hybrid virion and its nonhybrid adenovirus 7 counterpart was noted, the hybrid virion possessing the lower buoyant density. This difference in buoyant density appeared to be accentuated in a population of ad...
متن کاملBiophysical evidence for linkage of adenovirus and SV40 DNA's in adenovirus 7-SV40 hybrid particles.
The existence of virus particles in a strain of adenovirus 7 (E46+) consisting of simian virus 40 (SV40) genetic material inside an adenovirus 7 capsid has been demonstrated in several laboratories.'-3 These particles have variously been called "0)," "hybrid,"14 "transcapsidant," or "PARA."5 They are able to induce SV40 T and transplantation antigens, but not SV40 V antigen or virus. IUnderstan...
متن کاملShort hydrogen bonds and negative charge in photoactive yellow protein promote fast isomerization but not high quantum yield.
Biological signal transduction by photoactive yellow protein (PYP) in halophilic purple sulfur bacteria is initiated by trans-to-cis isomerization of the p-coumaric acid chromophore (pCa) of PYP. pCa is engaged in two short hydrogen bonds with protein residues E46 and Y42, and it is negatively charged at the phenolate oxygen. We investigated the role in the isomerization process of the E46 shor...
متن کاملStudies of Adenovirus Sv40 Hybrid Viruses
E46(+) virus purified by limiting dilution and plaque isolation in AGMK cells consists of a mixture of hybrid and non-hybrid virus particles. Of 102 plaque isolates obtained in HEK cells, 98 contained no detectable hybrid virus, while 4 contained a small proportion of hybrid virus. Plaque isolates from AGMK cells uniformly induced SV40 neoantigen, but when these plaque isolates were plaqued in ...
