Table 2. Overview of genes sequenced and their function.

Locus tag Gene Synonyms Function
PFLU_0088 kinB/algB   Regulatory two-component system (2CS) region that is involved in alginate biosynthesis
PFLU_0979 algA GMP, PMI, manA The two enzymatic activities of algA, GMP and PMI, are localized at the N- and C-terminals of the protein, respectively. GMP catalyzes the conversion of mannose-1-phosphage to GDP–mannose and PMI catalyzes the conversion of mannose-1-phosphate to GDP–mannose, which are required for the synthesis of alginate and the A-band of LPS
PFLU_0987 algK   Alginate polymerization
PFLU_0988 alg44   Alginate polymerization
PFLU_0990 algD GMD GDP–mannose dehydrogenase The alginate biosynthetic operon is under the transcriptional control of the algD promoter. algD encodes GMD, which is required for A-band LPS synthesis and irreversible oxidation of GDP–D-mannose to GDP–D-mannuronic acid (activated precursor for alginate polymerization)
PFLU_1467 algU algT or sigma factor-22 (σ22) Positive regulator of alginate biosynthetic operon
PFLU_1468 mucA   Negative regulator of alginate biosynthetic operon
PFLU_1469 mucB   Negative regulator of alginate biosynthetic operon
PFLU_1471 mucD   Negative regulator of alginate biosynthetic operon
PFLU_4443 FleQ   Regulates flagellum biosynthesis and is negatively regulated by algU
PFLU_4744 algZ   Alginate polymerization
PFLU_5986 algC PMM, PGM, GMP Encodes the bifunctional enzyme PMM/PGM that is required for both alginate biosynthesis, and addition of glucose and or/rhamnose into the growing core of LPS (O-side chains of LPS)
