Phospholipase A 2 and Phospholipase C Activities of Platelets DIFFERENTIAL
Deoxycholate treatment of horse platelets previously labeled in their phospholipids with [“Clarachidonate produces selective conversion of [“Clphosphatidylinositol (PI) to [‘4C]1,2-diacylglycerol. This phospholipase C activity, which has a pH optimum of 7.5, is specific for phosphatidylinositol since other phospholipids or neutral lipids are not affected. Although exogenous Ca2+ is not required...
متن کاملAction of Phospholipase C on the Thyroid
Treatment of dog thyroid slices with an enzyme present in the growth medium of Clostridium perjringens makes them unresponsive to thyroid-stimulating hormone (TSH) as measured by the oxidation of glucose-1J4C to 14C02. This enzyme appears to be phospholipase C since (a) both the anti-TSH effect and the phospholipase activity are inseparable over a 240-fold purification, (b) both activities are ...
متن کاملNMR structure of antibiotics plipastatins A and B from Bacillus subtilis inhibitors of phospholipase A(2).
Plipastatins A and B are antifungal antibiotics belonging to a family of lipopeptides capable of inhibiting phospholipase A(2) (PLA(2)) and are biosynthesised under certain circumstances by Bacillus subtilis. U-(15)N plipastatins A and B were obtained from cultures of the strain NCIB 8872 on a Landy medium modified for stable-isotope labelling by the substitution of the L-glutamic acid used as ...
متن کاملSTUDIES ON PHOSPHOLIPASE C FROM MELIA AZADIRACHTA SEEDS
The activity of phospholipase C in crude enzymatic preparation of Melia azadiracht seeds (Neem seeds) was studied by the use of lecithin as a substrate in aqueous medium. The enzyme activity was found optimum at pH 2.5 and temperature 35?C. The phospholipase C was found heat labile, being inactivated 88% within 10 minutes at 90°C
