Protein Family Models

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]. [1]. 7483254.

VgrG proteins of bacterial type VI secretion systems (T6SS), Pvc8 of the Photorhabdus virulence cassette, and related proteins of phage baseplate assemblies, all members of this family, share the property of occurring at the tip of cell-puncturing contractile injection systems.
