Accessory sec locus of S. gordonii M99 and domain organization of GspB. Upper diagram, map of the 23-kb M99 chromosomal locus containing gspB and the accessory sec genes. Asp1-5, SecY2, and SecA2 are components of the accessory Sec system. Gly, Nss, GtfA, and GtfB affect the glycosylation of GspB. Lower diagram, GspB polypeptide domains. SS, signal sequence; SRR1, first serine-rich region; BR, basic region; SRR2, second serine-rich region; CWA, cell wall-anchoring domain. GspB736flag is a variant of GspB that is truncated at residue 736 of 3,072 residues and has a C-terminal 3XFLAG tag.
