Adenosine deaminase acts as a natural antagonist for dipeptidyl peptidase 4-mediated entry of the middle East respiratory syndrome coronavirus
Journal of Virology , Volume 88 - Issue 3 p. 1834- 1838
Middle East respiratory syndrome coronavirus (MERS-CoV) replicates in cells of different species using dipeptidyl peptidase 4 (DPP4) as a functional receptor. Here we show the resistance of ferrets to MERS-CoV infection and inability of ferret DDP4 to bind MERS-CoV. Site-directed mutagenesis of amino acids variable in ferret DPP4 thus revealed the functional human DPP4 virus binding site. Adenosine deaminase (ADA), a DPP4 binding protein, competed for virus binding, acting as a natural antagonist for MERS-CoV infection.
