Retroviridae is a family of enveloped viruses that replicate in a host cell through the process of reverse transcription. A retrovirus is a single-stranded positive-sense RNA virus with a DNA intermediate and, as an obligate parasite, targets a host cell.ithin the cell, reverse transcriptase creates a complementary strand of DNA from the retrovirus RNA and the RNA is degraded; this strand of DNA is known as cDNA (4). The cDNA is then replicated, and the two strands form a weak bond and go into the nucleus (5).
The flavivirus C protein belongs to the same class of alpha-helical capsid proteins as the hepadnaviruses and retroviruses (31, 38). Similar structural motifs have also been observed in the core proteins of arteriviruses and bacteriophage Ï6 (9).ffect of capsid mutations on virus production. To study the effect of mutations in C protein on the viability of YFV, C-terminal truncations, internal deletions, and point mutations in the C-terminal helix were engineered into the full-length infectious cDNA clone of YFV.
