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 (By
CC       similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the alpha/beta-type SASP family. {ECO:0000305}.
