This domain is often found adjacent to the DHH domain Pfam:PF01368 and is called DHHA1 for DHH associated domain. This domain is diagnostic of DHH subfamily 1 members [1]. This domain is also found in alanyl tRNA synthetase e.g. Swiss:P00957, suggesting that this domain may have an RNA binding function. The domain is about 60 residues long and contains a conserved GG motif.
It is predicted that this family of proteins all perform a phosphoesterase function. This domain is found at the N-terminal of the single stranded DNA exonuclease RecJ. It shows an alpha-beta configuration [2].
