The protein envelope surrounding the virus was then reversed, in a process called antisense.

在一个称作反义的过程中，病毒外部的蛋白质包膜被反转。

That's not to say they aren't also complex: HIV envelope protein for instance is known to associate with 176 human proteins at the last count.

这并不是说它们也不复杂：例如，艾滋病毒的包膜蛋白是已知的与176种人类蛋白有关。

To test this possibility, Bieniasz's team engineered an unrelated mouse retrovirus coated with the envelope protein that would have allowed the ancient chimpanzee virus to slip into cells.

为了检验这种可能性，Bieniasz的团队设计了毫不相关的涂有包膜蛋白的老鼠反转录病毒，这种病毒容许黑猩猩病毒进入细胞。

The enzyme breaks up a virus's outer protein envelope into a mixture of mini-proteins known as peptides.

Three of four field tests conducted on the powder inside the envelope addressed to Wicker tested positive for a protein that later tests determined to be ricin, a lethal toxin, it says.
