The "swivelling" beta/beta/alpha domain (52008)
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
contains barrel, closed, n=7, S=10 Superfamily
structural similarity and possible distant homology to the phosphohistidine domain of pyruvate phosphate dikinase Superfamily
contains mixed beta-sheet barrel, closed n=7, S=10 Superfamily
