== Function ==
[https://www.uniprot.org/uniprot/IAA_STRTE IAA_STRTE] Inhibits mammalian alpha-amylases specifically but has no action on plant and microbial alpha-amylases. Forms a tight stoichiometric 1:1 complex with alpha-amylase.

== Publication Abstract from PubMed ==
The crystal and molecular structure of the alpha-amylase inhibitor Hoe-467A has been determined and refined at high resolution. The polypeptide chain is folded in two triple-stranded sheets, which form a barrel. The topology of folding is as found in the immunoglobulin domains. The amino acid triplet Trp18-Arg19-Tyr20 has an exceptional conformation and position in the molecule and is possibly involved in inhibitory activity.
