abstract：:To analyze proteolytic processing of foamy (spuma) retroviruses, two mutations were generated in the presumed active-site triplet Asp-Ser-Gly in the predicted proteinase (PR) region of the human foamy virus (HSRV).

For example, human cytomegalovirus induces quiescent cells to enter the cell cycle and then arrests them in late G(1), before they e...
