RT   the Streptococcus gordonii platelet-binding protein GspB.";
RL   J. Bacteriol. 187:3878-3883(2005).
CC   -!- FUNCTION: Part of the accessory SecA2/SecY2 system specifically
CC       required to export GspB, a serine-rich repeat cell wall protein encoded
CC       upstream in the same operon. {ECO:0000269|PubMed:15901716}.
CC   -!- SUBUNIT: Part of the accessory SecA2/SecY2 protein translocation
CC       apparatus required to export cell wall protein GspB.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Single-pass membrane
CC       protein {ECO:0000305}.
CC   -!- DISRUPTION PHENOTYPE: No export of mature cell wall protein GspB, a
CC       small amount of unprocessed protein is exported to the cell wall while
CC       the rest accumulates intracellularly, probably in a glycosylated form.
CC       Cells bind less well to platelets. {ECO:0000269|PubMed:15901716}.
