This entry represents the cupin domain, with a conserved jelly roll-like beta-barrel fold capable of homodimerisation found in bacteria, plant and fungi. It is present in EutQ family from the eut operon, involved in ethanolamine degradation. EutQ is essential during anoxic growth and has acetate kinase activity [1]. The cupin domain from EutQ does not possess the His residues responsible for metal coordination in other classes of cupins [2]. This domain is also found in (S)-ureidoglycine aminohydrolase (UGlyAH) from E.coli, which is involved in the anaerobic nitrogen utilisation via the assimilation of allantoin. It catalyses the deamination of allantoin to produce S-ureidoglycolate and ammonia from S-ureidoglycine [3,4].
