COMMENTARY 
LITERATURE
IMAGE
L-alpha-phosphatidylinositol 4,5-bisphosphate
1 mol%, 80% inhibition; strongest inhibitor among the phosphatidylinositols tested
-
lysophosphatidylcholine
-
the solubilized but not the microsomal enzyme is strongly inhibited
phosphatidylinositol-(4,5)-bisphosphate
80% inhibition at 1 mol%, CDS2 is inhibited by its anionic phospholipid end products, with phosphatidylinositol-(4,5)-bisphosphate showing the strongest inhibition; CDS1 is inhibited by their anionic phospholipid end products, with phosphatidylinositol-(4,5)-bisphosphate showing the strongest inhibition
dCTP
-
2.5 mM, 54% inhibition of purified enzyme; competitive with respect to CTP
diphosphate
-
2.5 mM, 80% inhibition of purified enzyme, noncompetitive with respect to CTP and phosphatidic acid
EDTA
the enzyme activity is almost completely inhibited when EDTA is added to the reaction
palmitoyl-CoA
-
inhibits incorporation of CTP into CDP-diglyceride in presence or absence of added phosphatidic acid
phosphatidylinositol
15-20% inhibition by soybean and liver phosphatidylinositol, inhibition of CDS2 by phosphatidylinositol is acyl chain-dependent, with the strongest inhibition seen with the 1-stearoyl-2-arachidonoyl species; CDS1 shows no acyl chain-dependent inhibition; significant inhibition of isoform CDS2 by both soybean and liver PI, with 15?20% residual activity
additional information
no significant inhibition in activity when either soybean or liver phosphatidylinositol is used at equimolar concentrations with respect to substrate. Neither soy nor egg phosphatidylglycerol has any significant inhibitory effect when used at equimolar concentrations with respect to substrate. Isoform CDS1 shows no acyl chain-dependent inhibition for 1-stearoyl-2-arachidonoyl-snphosphatidylinositol, 1-stearoyl-2-linoleoyl-sn-phosphatidylinositol, or 1,2-diolinoleoyl-sn-phosphatidylinositol
