The tape measure protein is not the longest protein in the genome, and it is located in an atypical region– amidst the genes that encode proteins found in the capsid.

BF phages have a large cassette of tRNAs, which will not be drawn on a Phamerator map. It will look like a gap in coding genes.

the terminase proteins are located near the center of the genome, downstream from all the minor tail proteins.

The immunity repressor is located just after the minor tail proteins and lysin, and the integrase is locate far downstream.

BD phages have a single endolysin, it should be labeled "lysin A".

Cluster BB contains some phages that were not isolated and sequenced by the SEA-PHAGES program. Their finders annotated the genomes differently. We are taking on the QC of these genomes but haven't reviewed the files yet.
These phages are:
phiC31, TG1, and phiBT1

Cluster BA contains some phages that were not isolated and sequenced by the SEA-PHAGES program. Their finders chose a different bp1 than we did, and annotated their genomes differently. We do not curate, update, or QC these genomes.

These phages are:
SPB78, Sros11, and VWB.

AV phages are myoviridae, and so encode tail tube and tail sheath proteins.

AV phages encode a large tail protein called a tail spike that is the functional equivalent of a tail fiber. It is large enough to be visible in the TEM, and its structural domains are based on beta-prisms and helices, rather than alpha coiled coils. The most famous example is the tail spike of Salmonella phage P22.
