Fig 1 For the first time, we are able to document the presence of long tail fibers with a sixfold symmetry attached to the base plate regions of A511, P100, and K (Fig. 1). These whiskers are distinct from the short tail spikes present on the lower side of the base plate structure, which are best visible in images of contracted phage tails (e.g., Fig. 1D), and also exhibit a sixfold symmetry. Interestingly, the base plates of all three phages seem to undergo quite dramatic conformational changes during tail contraction, allowing better visualization of its structure and components (Fig. 1A, C, D, and F). As a result of contraction triggering, the base plate moves upwards and the tail tube is exposed and extends beneath the base plate and tail sheath. Similar observations have been made for another SPO1-like phage, LP65 of Lactobacillus (9), which also appears to resembles A511 in morphology and approximate dimensions. Via the tips of exposed tail tubes in the contracted state, virions frequently adhere to some unstructured material, probably representing cell wall debris from lysed host cells (Fig. 1F). |
