Protein attributes

Sequence length	325 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Initiates the rapid degradation of small, acid-soluble proteins during spore germination By similarity.
Catalytic activity	Endopeptidase action with P4 Glu or Asp, P1 preferably Glu > Asp, P1' hydrophobic and P2' Ala. HAMAP MF_00626
Subunit structure	Homotetramer By similarity.
Post-translational modification	Autoproteolytically processed. The inactive tetrameric zymogen termed p46 autoprocesses to a smaller form termed p41, which is active only during spore germination By similarity.
Sequence similarities	Belongs to the peptidase A25 family.
