Family of bacterial and phage baseplate assembly proteins responsible for forming the small spike at the end of the tail or bacterial pathogenic needle-shaft [1]. This entry represents the OB fold part of the structure. This structure contains an unusual extra beta hairpin that forms the foundation of the spike protein's beta helix [3].	Domain
