CC   -!- FUNCTION: Involved in the biosynthesis of the antibiotic phenazine, a
CC       nitrogen-containing heterocyclic molecule. PhzB1 (operon
CC       phzA1B1C1E1F1G1) has a role in the biosynthesis of the phenazine during
CC       planktonic growth. {ECO:0000269|PubMed:23129634,
CC       ECO:0000305|PubMed:11591691}.
CC   -!- PATHWAY: Antibiotic biosynthesis; phenazine biosynthesis.
CC       {ECO:0000305|PubMed:11591691}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:Q9S508}.
CC   -!- INDUCTION: Under control of LasR (PubMed:11544214). In liquid cultures
CC       (aerobic), phz1 operon is induced by quinolone signal via 2-heptyl-3-
CC       hydroxy-4-quinolone (PQS) (PubMed:23129634). In biofilm (microaerobic),
CC       phz1 operon is not induced by PQS, because the biosynthesis of PQS by
CC       the monooxygenase PqsH requires molecular oxygen (PubMed:23129634).
CC       {ECO:0000269|PubMed:11544214, ECO:0000269|PubMed:23129634}.
CC   -!- SIMILARITY: Belongs to the PhzA/PhzB family. {ECO:0000305}.
