Viral structural protein

A viral structural protein is a viral protein that is a structural component of the mature virus.[1]

Examples include the SARS coronavirus 3a and 7a accessory proteins.[2][3]

Bacteriophage T4 structural proteins

During assembly of the bacteriophage (phage) T4 virion, the structural proteins encoded by the phage genes interact with each other in a characteristic sequence. Maintaining an appropriate balance in the amounts of each of these structural proteins produced during viral infection appears to be critical for normal phage T4 morphogenesis.[4] Phage T4 encoded proteins that determine virion structure include major structural components, minor structural components and non-structural proteins that catalyze specific steps in the morphogenesis sequence.[5] Phage T4 morphogenesis is divided into three independent pathways: the head, the tail and the long tail fibres as detailed by Yap and Rossman.[6]
