MAST3 pre-PK domain-like [140482] (1)
this domain precedes the Protein Kinase domain in Microtubule-associated serine/threonine-protein kinase 3 (MAST3) uperfamily
Bacillus cereus metalloprotein-like [158430] (1)
Duplication: tandem repeat of two domains of this fold with similar sequences; binds a dimetal ion cluster between the repeats
IVS-encoded protein-like [158446] (1)
IVS: Intervening sequence with conserved ORF in eubacterial 23S rRNA genes; forms a homopentamer with a toroid-shaped structure containing a tapered central channel
