tRNA components. Pth from Acinetobacter baumannii (Ab Pth) was cloned, expressed,
purified and crystallized in a native unbound (Ab Pth-N) state and in a bound state with the
phosphate ion and cytosine arabinoside (cytarabine)(Ab Pth-C). Structures of Ab Pth-N and
Ab Pth-C were determined at 1.36 and 1.10 Å resolutions, respectively. The structure of Ab
Pth-N showed that the active site is filled with water molecules. In the structure of Ab Pth-C, a …
