A	PF21923	BON-like domain (BON_like)	BON-like domain	This entry represents BON-like domain that appears to lack the first alpha helix of the classical BON domain structure.	Domain
A	PF04972	BON domain (BON)	BON domain	This domain is found in a family of osmotic shock protection proteins (e.g. Swiss:P27291). It is also found in some Secretins and a group of potential haemolysins. Its likely function is attachment to phospholipid membranes [1].	Domain
