Also known as
ECK1012; hmsR; ycdQ
Summary
PgaC complements a mutation in the homologous Y. pestis hemin storage gene hmsR. [More information is available at EcoGene: EG13863]. The pgaABCD locus is required for the synthesis of a cell-bound hexosamine-rich polysaccharide, which was identified as a linear polymer of beta-1,6-N-acetylglucosamine residues (PGA), an adhesin essential in biofilm formation . [More information is available at EcoCyc: G6529].
