Structural characterization of dUTPase from Legionella pneumophila
L. pneumophila serogroup 1 is the causative agent of Legionnaires' disease. Two crystal structures of apo and dUMP-bound deoxyuridine 5′-triphosphate nucleotidohydrolase (dUTPase) were determined to 1.80 and 1.95 Å resolution, respectively. dUTPases have been investigated as a potential druggable target in several pathogens.

If we take HIV's cousins & delete their dUTPase, they accumulate so many errors they either can't replicate in "old" cells, or it takes months longer for infection to become persistent.

So when HIV invades & begins using the "old" cell's DNA base pools, it finds weird or chemically damaged building blocks.
HIV's barnyard cousins, the "non-primate lentiviruses", that infect cats, goats etc., have specialized viral enzymes (dUTPase) that break down weird bases before they get used.
