Biology
Journal of Biological Chemistry
It is hypothesized that within the micro-environments of its host, this leishmanial “secretory” nuclease could function at a distance away from the parasite to harness (i.e. hydrolyze/access) host-derived nucleic acids to satisfy the essential purine requirements of these organisms.
