Tape measure in K1 phage

Link to this post \| posted 12 Jan, 2021 20:13
abeyer	While annotating K1 phage Jarvi recently, I came upon the longest gene which I automatically assumed would be tape measure (after tail assembly chaperone genes). However, upon looking at the PhagesDB data, a number of similar K1 phage are now calling this longest gene a minor tail protein (such as BarrelRoll and ActinUp) and they do not have a tape measure. Is there a reason for this switch? (was wondering if I missed a paper somewhere… ) Edited 12 Jan, 2021 20:13

debbie	Andrea, That is just incorrect. Gene 21 in ActinUp is the tape measure. debbie

abeyer	Thanks, Debbie, for the quick response and confirmation. Several phage genes then in that pfam (38675) are incorrect on phagesdb, as several are listed as minor tail proteins.
