Superfamily: LuxS/MPP-like metallohydrolase [63411]
Share the same "active site motif" HxxEH located in the first core helix, but differ in one of the zinc-binding residues uperfamily
MPP-like [63412] (10)
Common fold elaborated with many additional structures; duplication: each family member consists of two similar domains of beta(2)-alpha(2)-beta(2)-alpha(5)-beta structure, but only the N-terminal domain of MPP beta chain binds the catalytic metal
