1.   d.265.1       Pseudouridine synthase  the active site is the most conserved structural region of the superfamily and is located between the subdomains !   
                   Pseudouridine synthase consists of two alpha+beta subdomains with some similarity to the ferredoxin-like fold

2.   c.8.2         LeuD/IlvD-like  contains mixed beta-sheet barrel, closed n=7, S=10 !   
                   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
