Figure 2.
Fig. 2. Structural similarity of D3 to FABP. (A) A ribbon
diagram of M-FABP with a bound stearate (14). (B) Superposition
of LCF D3 (blue) and M-FABP (red). The D3 and FABP
helix-loop-helices differ, whereas the  -barrels are closely
aligned. An arrow shows the location of residue 1142. (C)
Alignment of primary and secondary sequences of D3 and M-FABP
within the -barrel region. Red and
purple residues are identical or similar, respectively, in the
two sequences. Two Gly-Gly sequences (boxes) are present in D3
but absent in M-FABP. -Strands 5-14 in D3
correspond to strands A-J in M-FABP.
