Fold: NAD(P)-binding Rossmann-fold domains [51734]
core: 3 layers, a/b/a; parallel beta-sheet of 6 strands, order 321456 The nucleotide-binding modes of this and the next two folds/superfamilies are similar
Family: Aminoacid dehydrogenase-like, C-terminal domain [51883]
extra N-terminal helix displaces the C-terminal helix (following strand 6) from its usual position creating a family nicotineamide-binding site
Methylenetetrahydrofolate dehydrogenase/cyclohydrolase [51894]
the two-domain organization is similar to that of aminoacid dehydrogenases, but both domains are truncated
