Partial purification and characterization of an exonuclease from Xanthomonas oryzae.

摘要

An exonuclease with a strong preference for single-stranded deoxyribonucleic acid over double-stranded deoxyribonucleic acid has been purified 500-fold from Xanthomonas oryzae. This enzyme liberates 5'-mononucleotides in a reaction which requires Mg2+.
