Enzymatic activity of lipase
The knowledge of the digestive system of bullfrogs is an important step for the determination of their nutritional requirements throughout growth phases. With the objective of evaluating the enzymatic activity of lipase in the intestinal content of bullfrogs (Rana catesbeiana Shaw, 1802), 100 animals with median weight of 3.6 g were distributed in stalls under controlled temperature and photope...
متن کاملDetermination of lipase activity.
Heretofore most methods for the determination of lipase activity have employed emulsions of fatty acid esters in water (1). These emulsions have been stabilized by use of such agents as gum acacia. The disadvantages of such methods are that (1) the emulsions break up to a considerable and variable extent during the course of the incubation, and (2) the enzyme is presumed to be in the aqueous ph...
متن کاملInfluence of active site and tyrosine modification on the secretion and activity of the Aeromonas hydrophila lipase/acyltransferase.
Aeromonas sp. secrete a lipase/acyltransferase that shares several properties with the mammalian plasma enzyme lecithin:cholesterol acyltransferase. Reaction of the enzyme with tetranitromethane led to modification of 2 tyrosines and a nearly 80% decline in enzyme activity. Replacing Tyr230 with Phe altered the activity of the enzyme in the same way as did treatment with tetranitromethane. Unli...
متن کاملEnzymatic Characterization of a Human Acyltransferase Activity
BACKGROUND Non-histone protein acylation is increasingly recognized as an important posttranslational modification, but little is known as to the biochemical properties of protein serine acylating enzymes. METHODOLOGY/PRINCIPAL FINDINGS We here report that we have identified a metal-stimulated serine octanoyltransferase activity in microsomes from human erythroleukemic (HEL) cells. The HEL ac...
