Eukaryotic viruses cannot infect bacteria. The cell wall is thick. The membrane has different protein (entrypoints) and then even if you transformed a bacterium with a viral genome on a plasmid it would not express because of promoters and very different codon bias. And... if you made a codon-optimised viral proteome under bacterial promoters and transformed it the assembled viral particles would not be able to get out.

HIV inserts its genome into the nuclear genome by using an enzyme, reverse transcriptase,  which copies the RNA as DNA. This same enzyme is used by humans to sequence RNA (the reverse transcribed version is called cDNA). Whereas Nanopore can actually read RNA the required processing for DNA samples is incompatible, so it was either gDNA or cDNA contamination during sample prep.

Bacteria are so numerous and so diverse that pretty much all sorts of oddities can happen, such as naked viral cDNA being absorbed and integrated via native recombinases. However, there are all sorts of "oh that's interesting" in environmental bacteria, but the truth is that only stuff that gets made into technology is looked at and that step requires a lot of effort. Say new enzymes, I have speculated the function of scores of enzymes and every time it I or others have placed then in the category "too much effort over publication impact".

The interesting numbers of an alignment are coverage (91%) and identity (82.68%) of API70200.1 (the protein encoded in KU749412) against WP\_199660587.

There are two cases:

* technical error: samples were contaminated, which happens not infrequently.
* biology did something cool: horizontal gene transfer

The former is likely to be present when you have a single sequence where this gene is present and it is not from a complete genome.

The latter, unless it's an ancient transfer, would likely result in flanking regions and genes.

So blasting the gene to the Klebsiella quasipneumoniae proteome, shows there are three hits (two poor). There is no strain name in list, whereas there are three complete genomes of three strains. So the sequence WP\_199660587 is a one off and not from a complete genome. Therefore, the clues strongly point towards it being a technical error.

> **username_1**: Bacteria are so numerous and so diverse that pretty much all sorts of oddities can happen, such as naked viral cDNA being absorbed and integrated via native recombinases. However, there are all sorts of "oh that's interesting" in environmental bacteria, but the truth is that only stuff that gets made into technology is looked at and that step requires a lot of effort. Say new enzymes, I have speculated the function of scores of enzymes and every time it I or others have placed then in the category "too much effort over publication impact".
