Publication Abstract from PubMed SpaP is a 1500-residue adhesin expressed on the surface of the caries-implicated bacterium Streptococcus mutans. SpaP is a member of the antigen I/II (AgI/II) family of proteins expressed by oral streptococci. These surface proteins are crucial for the incorporation of streptococci into dental plaque. The structure of the C-terminal domain of SpaP (residues 1136-1489) was solved and refined to 2.2 A resolution with six molecules in the asymmetric unit. Similar to a related AgI/II structure, SpaP is stabilized by isopeptide bonds between lysine and asparagine side chains.
