CC   -!- FUNCTION: Initiates the rapid degradation of small, acid-soluble
CC       proteins during spore germination. {ECO:0000255|HAMAP-Rule:MF_00626}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Endopeptidase action with P4 Glu or Asp, P1 preferably Glu >
CC         Asp, P1' hydrophobic and P2' Ala.; EC=3.4.24.78;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00626};
CC   -!- SUBUNIT: Homotetramer. {ECO:0000255|HAMAP-Rule:MF_00626}.
CC   -!- PTM: Autoproteolytically processed. The inactive tetrameric zymogen
CC       termed p46 autoprocesses to a smaller form termed p41, which is active
CC       only during spore germination. {ECO:0000255|HAMAP-Rule:MF_00626}.
CC   -!- SIMILARITY: Belongs to the peptidase A25 family. {ECO:0000255|HAMAP-
CC       Rule:MF_00626}.
