CC   -!- FUNCTION: Part of a capsular polysaccharide synthesis locus.
CC   -!- MISCELLANEOUS: Stealth proteins are part of a protein family that is
CC       conserved from bacteria to higher eukaryotes. Family members were first
CC       identified in microbes as proteins that help pathogens to elude the
CC       host innate immune system. Microbial stealth proteins are involved in
CC       the biosynthesis of exopolysaccharides. Stealth proteins are predicted
CC       to function as hexose-1-phosphoryltransferases.
CC   -!- SIMILARITY: Belongs to the stealth family. {ECO:0000305}.
