Expression of extracellular phospholipase from Serratia liquefaciens is growth-phase-dependent, catabolite-repressed and regulated by anaerobiosis.


Many members of the genus Serratia synthesize and excrete a number of extracellular hydrolytic enzymes. One of these is the phospholipase A1 from Serratia liquefaciens, the expression of which is growth-phase-dependent. Through the use of gene fusions and primer extension analysis we show that the expression of phospholipase is subject to positive… (More)
