Influence of antibodies to mannophosphoinositides on phospholipid synthesis in Mycobacterium smegmatis ATCC 607.
Antiserum to mannophosphoinositides had a significant inhibitory effect on phospholipid synthesis in Mycobacterium smegmatis ATCC 607 at different phases of growth; however, the inhibition was more pronounced in the exponential phase. The rate of synthesis of total phospholipids and individual phospholipids, viz., cardiolipin, phosphatidylethanolamine, and mannophosphoinositides, decreased in the presence of antiserum as compared with normal serum. The maximum inhibitory effect of antiserum was exerted on the synthesis of mannophosphoinositides, particularly on tetraacylated dimannophosphoinositide. Antiserum also had a growth inhibitory effect as compared with normal serum.
