This entry represents the NTF2-like domain found in the functionally uncharacterised YchJ family protein from Psychrobacter arcticus and related proteins. This domain is usually found flanked by either (Pfam:PF21612) and (Pfam:PF02810) at the N and C terminus or flanked on both sides by (Pfam:PF02810]). The structure of YchJ shows that this domain adopts structure typical for Nuclear transport factor 2 (NTF2) that consists of a curved three-stranded beta-sheet and array of alpha-helices packed on one side of it. The function of this domain is unknown.	Domain
A	PF02810	SEC-C motif (SEC-C)	SEC-C motif	This SEC-C motif is found in the C-terminus of the SecA protein, in the middle of some SWI2 ATPases and also solo in several proteins. The motif chelates zinc with the CXC and C[HC] pairs that constitute the most conserved feature of the motif [1-2]. ...	This SEC-C motif is found in the C-terminus of the SecA protein, in the middle of some SWI2 ATPases and also solo in several proteins. The motif chelates zinc with the CXC and C[HC] pairs that constitute the most conserved feature of the motif [1-2]. In SecA, this zinc binding domain is involved in binding to SecB [2]. This domain has been also predicted to be a potential nucleic acid binding domain.	Domain
