E1B-55K-mutant or E4orf6-mutant adenoviruses replicate more effectively after infecting cells in S phase than after infecting cells in G1. Enhanced S-phase replication of the E4orf6-mutant viruses requires the E4orf3 gene. This report demonstrates that the E4orf3 gene is also required for enhanced S-phase replication of the E1B-55K-mutant virus.
