Abstract
The vaccinia virus (VACV) precursor membrane, the crescent, consists of an open membrane sheet and is formed by rupture of a cellular compartment. Here, we asked whether A17, a viral membrane protein, plays a role in membrane rupture. Without A17 synthesis, crescents are not formed, and instead, tubular and vesicular membranes accumulate (Rodriguez et al. in J Virol 69:4640–4648,
1). We used electron tomography (ET) to analyze whether the viral membranes lacking A17 consist of open membrane sheets. Tubular, vesicular and so far not described onion-shaped membranes, which consisted of open membrane sheets, were seen. Thus, the data show that membrane rupture occurs independently of the A17 protein.
