Structural Classification of Proteins

Fold: LuxS/MPP-like metallohydrolase

: core: beta-alpha-beta(2)-alpha(2); 2 layers: alpha/beta

Lineage:

Root: scop
Class: Alpha and beta proteins (a+b) [53931]
Mainly antiparallel beta sheets (segregated alpha and beta regions)
Fold: LuxS/MPP-like metallohydrolase [63410]
core: beta-alpha-beta(2)-alpha(2); 2 layers: alpha/beta

Superfamilies:

LuxS/MPP-like metallohydrolase [63411] (2)
Share the same "active site motif" HxxEH located in the first core helix, but differ in one of the zinc-binding residues
uperfamily
1. Autoinducer-2 production protein LuxS [64294] (4)
  contains additional N-terminal strand; possible relationships to the putative editing domain of ThrRS (d.67.1)
  1. Autoinducer-2 production protein LuxS [64295]
    S-ribosylhomocysteinase
    1. Bacillus subtilis [TaxId: 1423] [64296] (6)
    2. Deinococcus radiodurans [TaxId: 1299] [64297] (5)
    3. Haemophilus influenzae [TaxId: 727] [64298] (2)
    4. Helicobacter pylori [TaxId: 210] [64299] (1)
2. 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
