Protein
Small, acid-soluble spore protein 1
Organism
Sporosarcina ureae
Function
SASP are bound to spore DNA. They are double-stranded DNA-binding proteins that cause DNA to change to an a-like conformation. They protect the DNA backbone from chemical and enzymatic cleavage and are thus involved in dormant spore's high resistance to UV light.
Similarity
Belongs to the alpha/beta-type SASP family.
