CommentThis HMM describes a family of bacteriophage proteins including G of phage lambda. This protein has been described as undergoing a translational frameshift at a Gly-Lys dipeptide near the C-terminus of protein G from phage lambda, with about 4 % efficiency, to produce tail assembly protein G-T. The Lys of the Gly-Lys pair is the conserved second-to-last residue of seed alignment for this family.
