COMMENTARY 
LITERATURE
IMAGE
Anti-HCE antibody
-
inhibits choriolytic swelling and binding to chorion, no effect on caseinolytic activity
-
antichoriolysin H
-
inhibits both choriolytic activity and binding to the egg envelope, does not affect caseinolytic activity
-
EDTA
-
succinyl-Leu-Leu-Val-Tyr 4-methylcoumarin 7-amide as substrate, 0.8 mM ZnCl2 restores or 80 mM CuCl2 partially restores, not NiCl2, MgCl2 or CaCl2
additional information
-
not inhibitory: diisopropylfluorophosphate, iodoacetic acid
-
additional information
-
no inhibition by monoiodoacetamide, monoiodoacetic acid or diisopropyl fluorophosphate
-
additional information
-
not inhibited by DFP, iodoacetamide or iodoacetic acid
-
additional information
-
the enzyme is very sensitive to trypsin-specific inhibitors, especially serine protease-specific inhibitors
