Genome sequencing of cellulolytic myxobacterium Sorangium cellulosum reveals many open-reading frames (ORFs) encoding various degradation enzymes with low sequence similarity to those reported, but none of them has been characterized. In this paper, a predicted lipase gene (lipA) was cloned from S. cellulosum strain So0157-2 and characterized. lipA is 981-bp in size, encoding a polypeptide of 3...

We analyzed the molecular defects in the lipoprotein lipase gene of a patient with type I hyperlipidemia suffering from recurrent pancreatitis, indicative for lipoprotein lipase deficiency. Postheparin lipoprotein lipase activity in the patient was decreased by 70%. Direct genomic sequencing revealed compound heterozygosity for two mutation: the well-known Gly188-->Glu and a new Val69-->Leu sub...

Mutated mouse lipoprotein lipase (LPL) containing a leucine (L) to histidine (H) substitution at position 452 was transferred into mouse liver by hydrodynamics-based gene delivery (HD). Mutated-LPL (MLPL) gene transfer significantly increased the concentrations of plasma MLPL and triglyceride (TG) but significantly decreased the activity of plasma LPL. Moreover, the gene transfer caused adiposi...

This study explored the potential of using the gene therapy approach, based on adenovirus-mediated expression of pancreatic lipase in the hepatobiliary tract, to increase lipid digestion in the intestinal lumen and promote lipid absorption through the gastrointestinal tract. Recombinant adenovirus containing the human pancreatic lipase cDNA (AdPL) was shown to transduce and mediate pancreatic l...

Molecular Modeling is essential tool in the drug design process describes the generation, manipulation or representation of 3D structures of the molecules and associated physico-chemical properties while docking predicts the preferred orientation of one molecule to a second when bound to each other to form a stable complex. A cold active lipase producing potential psychrophilic bacteria (GN) wa...

A partial (634 bp) cDNA clone, AF1229, obtained from expressed sequence tags (ESTs) of solid-cultured basidiomes of Antrodia cinnamomea is homologous to the lipase gene in Rhizomucor miehei. 5'-rapid amplification of cDNA ends (RACE) and 3'-RACE amplification showed that the full-length lipase gene, Ac-LIP, has a 912bp open reading frame (ORF), a 183bp 5' non-coding region, and a 144bp 3' non-c...

DsbA and DsbC proteins involved in the periplasmic formation of disulfide bonds in Pseudomonas aeruginosa were identified and shown to play an important role for the formation of extracellular enzymes. Mutants deficient in either dsbA or dsbC or both genes were constructed, and extracellular elastase, alkaline phosphatase, and lipase activities were determined. The dsbA mutant no longer produce...

LIGHT/TNFSF14 is a costimulatory molecule expressed on activated T cells for activation and maintenance of T cell homeostasis. LIGHT over expressed in T cells also down regulates hepatic lipase levels in mice through lymphotoxin beta receptor (LTβR) signaling. It is unclear whether LIGHT regulates hepatic lipase directly by interacting with LTβR expressing cells in the liver or indirectly by ac...
