BACKGROUND Pheromone biosynthesis activating neuropeptide (PBAN) is a neurohormone that regulates sex pheromone synthesis in female moths. Bombyx mori is a model organism that has been used to explore the signal transduction pattern of PBAN, which is mediated by a G-protein coupled receptor (GPCR). Although significant progress has been made in elucidating PBAN-regulated lipolysis that releases...

Aim. To identify the genes of false flax (Camelina sativa) endogenous lipases and to analyze sequence similarity their key functional domains with those commercially available lipases. Methods. A detailed search databases was carried out in order sequences various species, as well were aligned, conservative motifs identified, domain structure detected proteins established, phylogenetic analysis...

Lipase genes originating from the Gram-negative bacteria Serrutiu marcescens and Pseudomonus urruginosa were cloned. S. marcescens lipase was overexpressed in Escherichia coli yielding inclusion bodies which were purified and finally refolded to give enzymatically active lipase. The lipase operon of P. aeruginosa consisting of genes 1ipA and lip14 was cloned behind the T7 410 promoter and overe...
