Abstract |
The sn-glycerol-3-phosphate acyltransferase (plsB) catalyzes the first step in membrane phospholipid formation. A conditional Escherichia coli mutant (plsB26) has a single missense mutation (G1045A) predicting the expression of an acyltransferase with an Ala349Thr substitution. The PlsB26 protein had a significantly reduced glycerol-3-phosphate acyltransferase specific activity coupled with an elevated Km for glycerol-3-phosphate. |
