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].
