Protein
Phosphomannomutase/phosphoglucomutase
Gene
algC, PA5322
Organism
Pseudomonas aeruginosa (strain ATCC 15692 / PAO1 / 1C / PRS 101 / LMG 12228)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

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.2 Publications

Catalytic activityi

Alpha-D-mannose 1-phosphate = D-mannose 6-phosphate.
Alpha-D-glucose 1-phosphate = alpha-D-glucose 6-phosphate.

Cofactori

Binds 1 magnesium ion per subunit.
