Atu0741-like [143384] (1)
duplication: tandem repeat of two ACT-like domains; contains strand invasion of extra N-terminal strand into the C-terminal domain beta-sheet; dimerizes with the formation of orthogonally packed intersubunit beta-sheets
VC0802-like [143387] (1)
duplication: tandem repeat of two ACT-like domains; contains circular permutation (the C-terminal strand replacement with extra N-terminal strand); dimerizes with the formation of orthogonally packed intersubunit beta-sheets
Aspartokinase allosteric domain-like [143390] (3)
duplication: tandem repeat of two ACT-like domains; similar subunit and oligomeric structures to the VC0802-like family
BT0572-like [143395] (1)
duplication: tandem repeat of two ACT-like domains; dimerizes with the formation of orthogonally packed intersubunit beta-sheets
TM1266-like [160329] (1)
PfamB 015436; stand-alone tetrameric protein; there are single beta-sheet dimers, whose beta-sheets are packed in parallel fasion in the tetramer
