The aprX-lipA operon of Pseudomonas fluorescens B52: a molecular analysis of metalloprotease and lipase production.
Extracellular protease and lipase production by psychrotrophic strains of Pseudomonas fluorescens is repressed by iron and regulated by temperature. The regulation of protease and lipase has been investigated in P. fluorescens B52. Whereas lipase production is increased below the optimum growth temperature ('low-temperature regulation'), protease production was relatively constant and only decr...
متن کاملPurification and Characterization of a Thermostable Neutrophilic Metalloprotease from Pseudomonas sp. DR89
A novel neutrophilic metalloprotease was isolated from Pseudomonas sp. DR89 isolate which was identified ina mineral spring in Iran. The enzyme was purified from the isolate to 21-folds in a three-step procedure involving ammonium sulfate precipitation, Q-Sepharose ionic exchange and Sephadex G-100 gel filtrationchromatography. Resuts showed that the enzyme was active at high temper...
متن کاملIdentification, recombinant production and partial biochemical characterization of an extracellular cold-active serine-metalloprotease from an Antarctic Pseudomonas isolate
Cold-adapted enzymes are generally derived from psychrophilic microorganisms and have features that make them very attractive for industrial and biotechnological purposes. In this work, we identified a 50 kDa extracellular protease (MP10) from the Antarctic isolate Pseudomonas sp. AU10. The enzyme was produced by recombinant DNA technology, purified using immobilized metal affinity chromatograp...
متن کاملIron-mediated regulation of metalloprotease VvpE production in Vibrio vulnificus.
In Vibrio vulnificus, the production of metalloprotease VvpE is controlled by Crp (cAMP-receptor protein) and SmcR (a quorum sensing regulator) at the transcription level, and by PilD-mediated type II general secretion system (TTGSS) at the extracellular secretion level. Iron is known to stimulate VvpE production but the related mechanisms remain unidentified. Iron stimulated vvpE transcription...
متن کاملfaciliting lexical access for the fluent production of speech
the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis,a one-way anova experimental design was carried out. 24 sednior students of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inter...
