Comparative analysis of common regions found in babuviruses and alphasatellite molecules
Viruses in the genus Babuvirus have multi-component ssDNA genomes and often associate with alphasatellite molecules containing two common motifs, a common-region stem-loop (CR-SL) involved in initiation of rolling-circle replication and a common-region major (CR-M) motif involved in secondary-strand synthesis. We compared known babuvirus genome components and alphasatellite CR-SL and CR-M sequences, defining five divergent CR-SL sequence classes. We identified iterated sequence elements in babuvirus genome components that have particularly conserved sequences and spatial arrangements between known babuviruses.
