Description générale

Phospholipase A1 (PLA1) catalyzes the hydrolysis of acyl group from position 1 of lecithin to yield lysolecithin. It is expressed in a wide range of organisms such as rat platelets, bovine brain and testis, hornet venom, bonito muscle and fungi. Gene coding for PLA1 consists of four exons and three short introns spanning 1,056bp of genomic DNA. Mature protein contains 269 aminoacids and two possible N-glycosylation sites (Asn27 and Asn55).

Application

Phospholipase A1 from Aspergillus oryzae has been used:
  • in the preparation of sn-1 and sn-2 C18:1- lysophosphatidylcholine (LPC) regioisomer standards
  • as a catalyst for the synthesis 6-O-glucosyl-poly(3-hydroxyalkanoates) in a micro-aqueous system
  • to catalyze the synthesis of methyl butanoate and methyl benzoate flavor esters in continuous flow microreactor
  • to hydrolyze 17:0 phosphocholine (PC)

The lysis protein of the colicinogenic operon is essential for colicin release and its main function is to activate the outer membrane phospholipase A (OMPLA) for the traverse of colicin across the cell envelope. However, little is known about the

Here we have characterized the Rickettsia prowazekii RP534 protein, a homologue of the Pseudomonas aeruginosa ExoU phospholipase A (PLA) secreted cytotoxin. Our studies showed that purified recombinant RP534 PLA possessed the predicted PLA(2) and lyso-PLA(2) activities based on what has
