Although the figure was comparing to a nonsense mutation, the overall evidence for the activity for HK97 gp15 inhibiting phage infection came from the western blot which would be in accordance with evidence code IEP: Inferred from Expression Pattern.

None, yet.

I agree with your GO term and the evidence, but I think your reasoning could be stronger. Figure 4 could also be used as further evidence, as it supports the hypothesis that gp15 specifically prevents other phage DNA from entering the already infected cell. You might even want to consider creating a new GO term specifying that "superinfection exclusion through DNA entry prevention", to make the GO term fit even better.

GO:0098669 superinfection exclusion PMID:22797755 IMP: Inferred from Mutant Phenotype P Evidence from figure 1: western blot and plaque assays show HK97 gp15 inhibiting phage infection when compared to a nonsense mutation. It shows this by adding a transformed plasmid into the host cells, one where it expresses gp15 and the other with a nonsense mutation. When expressing gp15 it prevents the growth of HK97 and inhibits the growth of several related phages but there is no similar effect in the nonsense mutation implying that gp15 is the cause of super infection exclusion. complete

Interesting figure and paper. This is a better GO term than including the mechanism: "exclusion through DNA entry prevention," since it is not shown in Fig. 1, only the prevention of infection. However, a more detailed description of the figure is needed. It doesn't need to be long, but it does need to describe in the notes how Figure 1 shows the GO annotation in a couple sentences using the plaque assays to compare the different conditions and western blots to confirm the presence of the protein.
