The altered region corresponds to a turn between two short alpha helices.
The sequence Phe37Thr38Glu39 forms a turn between helices A and B and interacts with the unique extended C-terminus of Mtb SeMet-BfrA (154 159, Figure 10) which incidently in E. coli BfrA (shown in violet) loops in the other direction.
Starting from the strand containing residues 90/91/92, the short distance (2.2 nm) from 91 to 75/76 requires a turn between these strands.
In addition, the indole nitrogen forms a new H-bond with the carbonyl of G129, which resides on a turn between β-strands 4 and 5.
The probability of observing a turn between time t and (t +1 s) is: λ i (t) where the index i refers to the sensory experience associated with the ith run.
NAD binding involves numerous hydrogen-bonds and van der Waals contacts, in particular H-bonding of residues in a turn between the first strand and the subsequent helix of the Rossmann-fold topology.

The patatin domain shares a conserved core module with mammalian lipases, where the nucleophilic serine is located in a tight turn between a β-sheet and an α-helix in a well conserved β- β- α- β core structure [ 17] which is also present in, e.g., human cytosolic phospholipase A2 [ 18].
The p.P474T mutation alters a highly conserved proline residue located in a turn position between β3-strand and α2-helix (Fig 2C).
