DromeQC belongs to the α/β-hydrolase fold superfamily; this superfamily exhibits a β-sheet core (5-8 strands) connected to α helices forming an α/β/α sandwhich<ref name=“family”>PMID: 23193256</ref>. As of present, the ESTHER database (ESTerases and α/β-Hydrolase Enzymes and Relatives) contains 168 protein families<ref>Lenfant, N., Hotelier, T., Velluet, E., Bourne, Y., Marchot, P., and A Chatonnet.

It is interesting that DromeQC prevents protein degradation from aminopeptidases, yet theses two enzymes share a common fold and active site residues<ref>PMID: 15028118</ref>. This suggests that the enzymes act in a similar manner, with contrasting effects on substrate.
