Abstract:
:Statistically significant sequence similarity was revealed between the gene A32 product of vaccinia virus (VV), gene I products (gpI) of filamentous single-stranded DNA bacteriophages, and IVa2 gene products of adenoviruses. Four conserved sequence motifs were delineated, the two N-proximal of which correspond to the A and B motifs of the purine NTP-binding pattern. Based on the role of gpI and IVa2 proteins in virion morphogenesis, and on the conservation of the NTP-binding pattern in these proteins, we hypothesize that the A32 gene product might be involved in an ATP-consuming function in VV virion formation, e.g., packaging of the DNA in the virus particle.
