The cryo structure shows that the channel is 9 nm wide, tapering to a point, and a homology model of the pilus (based on the N. gonorrhoeae pilus) is shown to be 6.5 nm wide (Collins et al. 2003).
In comparison, the closed state of Neisseria meningitidis PilQ is ∼9 nm wide tapering to a point (Collins et al., 2004), which would be sufficient to accommodate the wider Neisseria pilus (Collins et al., 2003; Craig et al., 2006) after a comparably large conformational change.
With rather little species variation, these ciliated cells are columnar in the trachea and large bronchi (approximately 20 μm long and 7 μm wide, tapering to 2 μm at the basement membrane) and then decrease in height towards small bronchi and bronchioli (Lee and Forrest 1997).
Australian fur seal bulls are larger and heavier but less stocky with a long head and wider, tapering, but blunter muzzle with a large rhinarium that extends well beyond the mouth.
The precast concrete barriers along the Gold Line are just shy of three feet high, with a familiar K-rail shape: a wide base that tapers slightly to a straight, vertical wall.
It is especially good if the glass has a wide mouth with a tapered bottom.
A brandy snifter or brandy balloon is a short glass with a wide base whose sides taper in at the top.
Related to the hu in profile, the you consisted of a base, usually oval in section, and a broad body, slightly swollen at the centre and tapering to a wide neck.
A widespread species with a cosmopolitan distribution, it is a medium-sized puffball with a round fruit body tapering to a wide stalk, and dimensions of 1.5-6 cm wide by 3-7 cm tall.
Using a compound microscope equipped with differential interference contrast, further scorable characters are the presence of a round median pharyngeal bulb, the characteristic vulva cell division pattern [ 2], and the shape and arrangement of rays in the male tail, including a ray 6 that lacks a tip opening to the outside and which tapers from a wide base [ 12].
The New Yorker, October 22, 1932 P. 24 Blennies are light-minded fishes with tapering tails and a wide distribution.
