This domain is found at the N-terminal of the chaperone SurA, a chaperone that assists correct folding of outer membrane proteins (OMPs) in Gram-negative bacteria [1]. This is the helical domain found at the N-terminal of SurA that, together with the C-terminal, forms a core domain which contains OMP binding sites. OMP binding induces conformational changes of SurA domains that protect OMPs from misfolding and aggregation [2]. The C-terminal of the SurA protein folds back and forms part of this domain also but is not included in the current alignment.	Domain

This domain is found at the C-terminal end of the possible periplasmic protein Swiss:Q0P8W8 from Campylobacter jejuni (Cj1289) and similar sequences mainly found in epsilonproteobacteria. This domain is normally associated to Pfam:PF09312. It shows an alpha-beta configuration. Its specific function is unknown.	Domain
