(a) AlphaFold3 model of ΦCD508 gp67, a putative baseplate attachment protein forming part of the tail fibre. (b) AlphaFold3 model of ΦCD508 gp68, a putative RBP of the tail fibre assembly. (c) X-ray crystallographic structure of the putative receptor-binding domain of PtsM from Φ027. Individual chains are coloured along with a coordinated metal ion (green). (d) AlphaFold3 model of a putative full-length PtsM dimer from Φ027. The C-terminal putative receptor-binding domain adopts the same fold as the experimental structure in (c). (e) AlphaFold3 model of dimeric PtsHN10M; the putative RBP domain is at the bottom. The coloured scale bar indicates pLDDT (predicted local distance difference test) values.
