This type of transporter associated with expression of extracellular lipases or phospholipases (like LipA or PlcB) could allow P. aeruginosa to degrade phosphatydylethanolamine [67] or phosphatydylcholine [69] as one nutrient source, for example in the lungs of cystic fibrosis patients. The gene discussed is LIPA; the disease is cystic fibrosis.
