what are the capsid proteins in yellow fever
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 Ï6 (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.
