O-antigen polysaccharides found on the outer surface of bacteria are the natural substrates for TSP[2]. Relevance Bacteriophage research is becoming important due to antibiotics resistance. TSP binding to pathogenic bacteria can be used for their detection[3]. Structural highlights The N-terminal domain (NTD) (residues 1-108) of TSP is responsible for the attachment
