Abstract:
The effect of calcium on the structural and functional aspects of phospholipids in Microsporum gypseum was examined. Cells grown in presence of calcium exhibited increased content of phospholipids and enhanced synthesis of phospholipids as monitored by the incorporation of [32P] orthophosphoric acid. The rise in the levels of phospholipids was found to be due to increased synthesis of fatty acids as observed from [14C] acetate incorporation studies. The rise in the levels of phospholipids were reflected in the subcellular fractions also. Change in the phospholipid composition increased the fluidity of the membrane as is evident from fluorescence polarization studies using 1-anilinonaphthalene-8-sulfonate (ANS) and 1,6-diphenyl-1,3,5-hexatriene (DPH). The increased membrane fluidity was consistent with the enhanced uptake of [3H] proline in calcium grown cells.
