Abstract

An acid deoxyribonuclease of guinea pig epidermis hydrolyzes chromatin DNA as well as histone-free DNA. The enzyme degrades approximately 50% of chromatin DNA, while it degrades 90% of histone-free DNA. Guinea pig epidermal extract contains proteolytic activity for histone or chromatin with a pH optimum at around 8.0.
