Non-canonical RNA-polymerases of ϕKZ-like phages

Biophysics and medical physics

Nine ϕKZ-like bacteriophages, encoding their own RNA polymerase (RNAP), belonging to the class multi-subunit RNAP, were found in a database of complete genomes. Analysis of protein sequences and genetic environment of RNAP genes have suggested the presence of two independent functional phage RNAP, “virion” and “non-virion”.
