This domain has no known function and is found in conserved hypothetical archaeal and bacterial proteins. The domain is duplicated in Swiss:O53566. The structure of a DUF35 representative reveals two long N-terminal helices followed by a rubredoxin-like zinc ribbon domain represented in this family and a C-terminal OB fold domain. Zinc is chelated by the four conserved cysteines in the alignment.	Domain

The structure of a DUF35 representative reveals two long N-terminal helices followed by a rubredoxin-like zinc ribbon domain and a C-terminal OB fold domain represented in this entry. OB-folds are frequently found to bind nucleic acids suggesting this domain might bind to DNA or RNA (Topsan http://www.topsan.org/). Genomic context shows it to be adjacent to acyl-CoA transferase (http:/www.microbesonline.org/).	Domain
