1.   c.8.4         PA domain    
                   The "swivelling" beta/beta/alpha domain 3 layers: b/b/a; the central sheet is parallel, and the other one is antiparallel; there are some variations in topology ! this domain is thought to be mobile in most multi-domain proteins known to contain it
