A	PF02272	DHHA1 domain (DHHA1)	DHHA1 domain	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, suggest ...	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.	Domain
A	PF20748	RecJ C-terminal domain, Deinococci (RecJ_C_Deinoc)	RecJ C-terminal domain, Deinococci	This domain is found at the C terminus of Single-stranded-DNA- specific exonuclease RecJ from Deinococci. This protein has four domains that form a molecule with an O-like structure [1]. The fourth domain (this entry) binds the C-terminal region of S ...	This domain is found at the C terminus of Single-stranded-DNA- specific exonuclease RecJ from Deinococci. This protein has four domains that form a molecule with an O-like structure [1]. The fourth domain (this entry) binds the C-terminal region of Single-stranded DNA-binding protein (Pfam:PF00436) to efficiently process broken DNA ends for homologous recombination [2].	Domain
A	PF01368	DHH family, N-terminal domain (DHH)	DHH family, N-terminal domain	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].	Domain
A	PF17768	RecJ OB domain (RecJ_OB)	RecJ OB domain	This OB-fold is found in RecJ proteins where is binds to ssDNA [1].	Domain
