Phospholipase A1 - an overview ScienceDirect Topics
WebThis phospholipase C-γ isozyme is activated by binding to a specific phosphorylated tyrosine on the cytoplasmic side of the receptor after ligand binding (2). 1,4,5-Triphosphate (IP 3) diffuses to the ER where it opens 1,4,5-triphosphate (IP 3)-gated Ca 2+ channels (3). Phospholipase A1 (EC 3.1.1.32; systematic name: phosphatidylcholine 1-acylhydrolase) encoded by the PLA1A gene is a phospholipase enzyme which removes the 1-acyl group: phosphatidylcholine + H2O = 2-acylglycerophosphocholine + a carboxylate It is an enzyme that … See more PLA1's are present in numerous species including humans, and have a variety of cellular functions that include regulation and facilitation of the production of lysophospholipid mediators, and acting as digestive enzymes. … See more There are many variations of PLA1, differing slightly between each organism it is present in. Most notably, it can be found in mammalian cells … See more The structure of a PLA1 is a monomer that contains the following sequence: Gly-X-Ser-X-Gly, where X represents any other amino acid. The serine is considered the active site in the enzyme. PLA1's also contain a catalytic triad of Ser-Asp-His, with a variety of … See more In the early 1900s, an observation was made, showing an accumulation of free fatty acids after incubation of pancreatic juice with phosphatidylcholine. One of the first cases of … See more PLA1 hydrolyzes nonionic substrates preferentially over ionic substrates. Optimum pH conditions for PLA1 activity on neutral phospholipids is around 7.5, whereas the … See more Unlike other phospholipases such as PLA2, there is much that is unknown about PLA1 due to the lack of any efficient way to purify, clone, express, and characterize this enzyme. PLA1 is currently commercially unavailable because of this. … See more • Outer membrane phospholipase A1 See more the park vancouver apartments
