        SQ Q9QY93 22-134
  2. AF0060-like [140794] (1)
    consists of a single member with an orphan sequence; "circular permutation" of putative active site residues: the catalytic lysine resides in the N-terminal helix instead of the missing in this family C-terminal helix; probable biological unit is a tertramer, distinct from the MazG family tetramer
