Cluster CX phages contain a gene that encodes a protein very similar to the integrases of the temperate phages. However, these phages do not contain any other identifiable integration machinery–immunity repressor, CRO, excise, etc; nor have we been successful in isolating lysogens. Therefore, we've decided that the "integrase" is better off labeled as "recombinase".

sounds like you are making a strong case for including the more specific one. Which way are you leaning on this?

yep.

I don't really like the name "super -infection immunity protein" because there are too many different types of proteins that can accomplish that phenotype.

Lysin A is near the left end of the genome, Lysin B is two genes upstream from the tape measure protein.

Cluster DJ phages have two genes that are predicted to encode major tail proteins with good bioinformatic support. This has not been demonstrated at the bench yet, however, we are going to label both with the functional label "major tail protein".

The capsid maturation protease, scaffolding, and major capsid protein are fused in cluster DJ phages.

Lysin A, which is a single multi-domain protein in many Actinobacteriophages, is split at the domain boundaries encoded by two adjacent genes in members of cluster DI. The functions should be reported as "lysin A, whatever the domain is" to indicate that each gene does not encode the full lysin A.

We do not know where the frameshift is in the DH tail assembly chaperones.

Lysin B is not adjacent to lysin A in cluster DG, instead it is at the end of the right arm of the genome.
