Figure 5 shows "SDS-PAGE of an expression vector assay of the φKZ protease showing cleavage of φKZ head protein gp93."

From first two paragraphs under the "Identification of φKZ gp175 as the morphogenetic protease" says "we used local implementations of the Sequence Analysis and Modeling System and HHpred.The E-value of this match was only 3, however the HHpred P-value, which takes secondary structure into account, was 2.5E-05. This match was solidified using a custom T4 gp21 HHM powerful enough to detect an HHM based on the U35 peptidase family at E-values of 3.5E-05. Members of the U35 peptidase family contain diverged, but known, homologs to the T4 protease, such as the HK97 protease."

Figure 2 shows the location of the phage DNA where the prohead protease cleaves.

Figure 1. SDS-Page and Mass Spec shows the size and boundaries of the genes cleaved by the prohead protease.

From the fourth paragraph under results,"in the course of expanding the U35.001 family, we found statistical evidence that the U9 family and the U35.001 family are remote homologs. For example, starting with the U35.001 representative HK97 gp4 protease (gi|9634157, residues 1–225), PSI-BLAST search found a close homolog gi|26988298 with e-value 2e-18 in the first iteration. Using this sequence as query to run PSI-BLAST (default parameters in NCBI Web site), we found a U9 family member (gi|30044105) in the third iteration with a significant e-value 0.003."

Figure 2A Euclidian distance map. "In distance mapping, each sequence is represented by a point in a multidimensional Euclidian space and the distances between these points reflect the evolutionary distances between the sequences. A two-dimensional projection of this space is shown in Figure 2A ▶ (below). This plot offers a visualization of the sequence clustering; each family or subfamily appears as a rather distinct group, except for U35.002.a and U35.002.c. These two subfamilies are divided on the basis of sequence conservation and insertion/ deletion patterns."
