Figure 2 Stereo C[ ]superposition
of Tfi DNA ligase. (A) One of the two crystallographically
independent ligase molecules in the native structure takes a
more closed conformation (gray) than the other (black), and its
BRCT domain is visible in the electron density map.
Superposition is made for domain 1. (B) Subdomain 1a of Bst
ligase (gray) takes a very different orientation from that of
Tfi ligase (black). Superposition is made for subdomain 1b.
