CC -!- FUNCTION: SASP are bound to spore DNA. They are double-stranded DNA-
CC binding proteins that cause DNA to change to an a-like conformation.
CC They protect the DNA backbone from chemical and enzymatic cleavage and
CC are thus involved in dormant spore's high resistance to UV light.
CC -!- MISCELLANEOUS: SASP are degraded in the first minutes of spore
CC germination and provide amino acids for both new protein synthesis and
CC metabolism.
CC -!- SIMILARITY: Belongs to the alpha/beta-type SASP family. {ECO:0000305}.
