Pseudoalteromonas rubra S4059 produces the red pigment prodigiosin, which has pharmaceutical and industrial potential. Here, we targeted a putative prodigiosin-synthesizing transferase PigC, and a pigC in-frame deletion mutant did not produce prodigiosin. However, extractions of the pigC mutant cultures retained
