[https://www.uniprot.org/uniprot/ALGC_PSEAE ALGC_PSEAE] The phosphomannomutase activity produces a precursor for alginate polymerization. The alginate layer causes a mucoid phenotype and provides a protective barrier against host immune defenses and antibiotics. Also involved in core-LPS biosynthesis due to its phosphoglucomutase activity. Essential for rhamnolipid production, an exoproduct correlated with pathogenicity, and for biofilm production.<ref>PMID:7515870</ref> <ref>PMID:10481091</ref>

The enzyme phosphomannomutase/phosphoglucomutase (PMM/PGM) from P. aeruginosa is required for the biosynthesis of two bacterial exopolysaccharides: alginate and lipopolysaccharide (LPS). Both of these molecules play a role in the virulence of P. aeruginosa, an important human pathogen known for its ability to develop antibiotic resistance and cause chronic lung infections in cystic fibrosis patients. The crystal structure of PMM/PGM shows that the enzyme has four domains, three of which have a similar three-dimensional fold. Residues from all four domains of the protein contribute to the formation of a large active site cleft in the center of the molecule. Detailed information on the active site of PMM/PGM lays the foundation for structure-based inhibitor design. Inhibitors of sufficient potency and specificity should impair the biosynthesis of alginate and LPS, and may facilitate clearance of the bacteria by the host immune system and increase the efficacy of conventional antibiotic treatment against chronic P. aeruginosa infections.
