Inhibits host cell division leading to filamentation (PubMed:24210121). Does not prevent host cell growth, DNA synthesis or chromosome segregation (PubMed:24210121). Does not seem to be essential for productive bacterial host infection (PubMed:24210121). Disrupts inhibition of host cell division (PubMed:24210121). Has no effect on host DNA synthesis, burst size or latent period during infection (PubMed:24210121).
