CC   -!- FUNCTION: Required for the synthesis of poly-beta-1,6-N-acetyl-D-
CC       glucosamine (PGA), a biofilm adhesin polysaccharide. May assist the
CC       glycosyltransferase PgaC in the polymerization of PGA.

CC       P69432; P75905: pgaC; NbExp=2; IntAct=EBI-562069, EBI-561450;
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane
CC       {ECO:0000269|PubMed:15919996}; Multi-pass membrane protein
CC       {ECO:0000269|PubMed:15919996}.
CC   -!- INDUCTION: Levels of this protein are positively controlled by the
CC       second messenger c-di-GMP (at protein level) at a post-transcriptional
CC       level. Increased levels of c-di-GMP lead to increased levels of PgaD.
CC       {ECO:0000269|PubMed:19460094}.
CC   -!- DISRUPTION PHENOTYPE: Cells lacking this gene do not synthesize PGA.
CC       {ECO:0000269|PubMed:15090514, ECO:0000269|PubMed:18359807}.
