Schematic representations of the ICP22 open reading frame of wild-type and mutant HSV-1 showing the location of methionine codons. Line 1, positions of the four methionine codons in the first 200 amino acids of HSV-1. Line 2, R7815 (Δα22NT/US1.5)[Δ47a.a.] lacking 47 amino acids deleted from the amino terminus. The first methionine available for translational initiation is at codon 90. Line 3, R7805 (Δα22NT/US1.5)[Δ138a.a.], lacking the amino-terminal 138 amino acids. The first methionine available for translational initiation is at codon 147. Line 4, R7808 (Δα22NT/US1.5)[Δ171a.a.] lacking amino-terminal 170 amino acids. The first methionine available for translational initiation is at codon 171.
