Studies on nutritional requirements of Pseudomonas aeruginosa for lipase production
A nutritional requirement for the lipase production by Pseudomonas aeruginosa strain was investigated. The bacterial strain was isolated from municipal sewage and it was culture with different nutritional composition. The maximum lipase activity was obtained with maltose as the sole carbon source 6.5 Uml, followed by lactose 4.6Uml . The various salts used the best results were observed with ca...
متن کاملEvidence of a Double-Lid Movement in Pseudomonas aeruginosa Lipase: Insights from Molecular Dynamics Simulations
Pseudomonas aeruginosa lipase is a 29-kDa protein that, following the determination of its crystal structure, was postulated to have a lid that stretched between residues 125 and 148. In this paper, using molecular dynamics simulations, we propose that there exists, in addition to the above-mentioned lid, a novel second lid in this lipase. We further show that the second lid, covering residues ...
متن کاملExtracellular lipase from Pseudomonas aeruginosa is an amphiphilic protein.
Lipase (triacylglycerol acylhydrolase, EC 3.1.1.3) secreted by Pseudomonas aeruginosa PAC1R was purified from cell-free growth medium by preparative isoelectric focusing. After blotting the N-terminal amino acid sequence and the amino acid composition were determined and compared to P. fragi and P. cepacia lipases yielding significant homology between all three species. Additionally, a consensu...
متن کاملStructural basis of the chiral selectivity of Pseudomonas cepacia lipase.
To investigate the enantioselectivity of Pseudomonas cepacia lipase, inhibition studies were performed with Sc- and Rc-(Rp,Sp)-1,2-dialkylcarbamoylglycero-3-O-p-nitrophenyl alkylphosphonates of different alkyl chain lengths. P. cepacia lipase was most rapidly inactivated by Rc-(Rp,Sp)-1,2-dioctylcarbamoylglycero-3-O-p-nitrophenyl octylphosphonate (Rc-trioctyl) with an inactivation half-time of ...
متن کاملStructural insights of a hormone sensitive lipase homologue Est22
Hormone sensitive lipase (HSL) catalyzes the hydrolysis of triacylglycerols into fatty acids and glycerol, thus playing key roles in energy homeostasis. However, the application of HSL serving as a pharmaceutical target and an industrial biocatalyst is largely hampered due to the lack of high-resolution structural information. Here we report biochemical properties and crystal structures of a no...
