In light of SARS-COV-2 binding to the ACE 2 protein in human cells, I was wondering if any bacteria exist or could exist that possess this membrane protein. If not, do you believe that an ACE 2 like protein https://www.jstage.jst.go.jp/article/jpssuppl/92/0/92_2-YIA-09/_pdf expressed by a bacteria could allow the COVID-19 virus to successfully attach and be fused into the bacterium?
Short answer is no, because the ACE2 receptor is only a trigger (and anchoring point) for endocytosis. The endocytosis requires many enzymes/proteins which are (as far as I know) specific to eukaryotes. You'd need to express those too in your bacterium and the lack of adequate eukaryote-like transport protein in your bacterium will likely forbid the whole from functioning.
