Figure 6.
Structural comparison of Ins(1,4,5)P3 (1), AdA and some of its truncated analogues including α-d-glucopyranosyl 1,3,4-trisphosphate (6) and β-d-glucopyranosyl 1,3,4-trisphosphate (7). The conserved regions of the structures involved in binding are drawn in blue while the differing auxiliary phosphate is shown in red.
