일반 설명
Phospholipase A2 is a small disulfide-rich protein having 124 residues. It is a calcium-dependent enzyme.
애플리케이션
Phospholipase A2 has been used in phospholipase assay and to determine rat renal proximal tubular segments (PTS) viability during oxygenation and hypoxia-reoxygenation.
생화학적/생리학적 작용
It has a high catalytic activity on aggregated substrates compared to monomeric substrates.
Hydrolyzes the β-ester bond of zwitterionic glycerophospholipids. Preferred substrates are phosphatidylcholine, phosphatidylethanolamine, and their plasmalogen analogues. Phosphatidylinositol and phosphatidylserine are also hydrolyzed. Aggressively attacks phospholipids in membranes of intact cells.
단위 정의
One unit will hydrolyze 1.0 μmole of soybean L-α-phosphatidylcholine to L-α-lysophosphatidylcholine and a fatty acid per min at pH 8.0 at 37 °C.
물리적 형태
Suspension in 3.2 M (NH4)2SO4 solution, pH 5.5

Porcine pancreatic phospholipase A2, a small and disulfide rich protein, is extremely resistant against chemically or thermally induced unfolding. Despite this marked resistance, the protein displays broad unfolding transitions resulting in comparatively low apparent thermodynamic stability. Broad unfolding transitions may

During hypoxic or ischemic renal tubular injury, phospholipase A2 (PLA2) induces membrane deacylation, causing fatty acid accumulation and phospholipid breakdown. Because these changes can compromise cellular integrity, PLA2 activity has been widely proposed as a critical mediator of hypoxic renal

Cholesterol and phospholipid concentrations and phospholipase activity were measured in fluid from cannulae collected from the bovine oviductal isthmus and ampulla at different stages of the oestrous cycle. The cholesterol concentration and cholesterol normalized by protein were significantly (P =

Bile salt stimulated lipase (BSSL; Enzyme Commission (EC) number 3.1.1.13) has been a candidate triglyceridase for improving enzyme therapy for pancreatic insufficiency; however, its efficacy is near absent. We hypothesise that similarly to pancreatic lipase, BSSL is inhibited by phospholipids
