Bacillus virus Φ29 (bacteriophage Φ29) is a double-stranded DNA (dsDNA) bacteriophage with a prolate icosahedral head and a short tail that belongs to the genus Salasvirus, order Caudovirales, and family Salasmaviridae. [2] [3] They are in the same order as phages PZA, Φ15, BS32, B103, M2Y (M2), Nf, and GA-1.INTRODUCTION. The viral DNA-packaging motor of dsDNA bacteriophage (e.g. phi29, lambda, T4 and T7) can translocate and compress genomic DNA with tremendous velocity into a preformed protein shell, called the procapsid, fueled by hydrolysis of ATP during assembly (1–6).The procapsid of …The pRNA (packaging RNA) of bacteriophage phi29 DNA packaging motor has been reported to have novel applications in nanotechnology and nanomedicine. The unique ability of pRNA to form dimers, trimers, hexamers and patterned superstructures via the interaction of two reengineered interlocking loops m …May 30, 2023 · Abstract.
