Engineering of a single conserved amino acid residue of herpes simplex virus type 1 thymidine kinase allows a predominant shift from pyrimidine to purine nucleoside phosphorylation.
Studies of herpes simplex virus type 1 (HSV-1) thymidine (dThd) kinase (TK) crystal structures show that purine and pyrimidine bases occupy distinct positions in the active site but approximately the same geometric plane. The presence of a bulky side chain, such as tyrosine at position 167, would no...
