This entry represents a SAM-like helix-hairpin-helix domain found in functionally diverse proteins involved in DNA repair, recombination, transcription termination etc. This domain has a fold that is structurally similar to SAM domains. It is composed of two helix-hairpin-helix motifs which are known DNA interaction motifs.	Domain
