Gene cloning and expression and secretion of Listeria monocytogenes bacteriophage-lytic enzymes in Lactococcus lactis.
Bacteriophage lysins (Ply), or endolysins, are phage-encoded cell wall lytic enzymes which are synthesized late during virus multiplication and mediate the release of progeny virions. Bacteriophages of the pathogen Listeria monocytogenes encode endolysin enzymes which specifically hydrolyze the cross-linking peptide bridges in Listeria peptidoglycan. Ply118 is a 30.8-kDa L-alanoyl-D-glutamate p...
متن کاملCloning of EprA1 gene of Aeromonas hydrophila in Lactococcus lactis
Bacterial-based systems as live vectors for the delivery of heterologous antigens offer a number of advantages as vaccination strategies. Developments in genetic engineering have given Gram-positive lacticacid bacteria (LAB) the advantage of being used as a host expression system for antigen delivery to inducethe immune response. A fragment containing the full length of the “eprA1” ...
متن کاملکلونینگ و بیان ژن hly Listeria monocytogenes در Lactococcus lactis
ژن hly یکی از مهم‌ترین عوامل ویرولانس Listeria monocytogenes می‌باشد که پروتئین لیستریولیزین (O (LLO را رمزگذاری می‌کند. LLO یک پروتئین ایمونوژن با قابلیت بالاست، که قادر به برانگیختن ایمنی سلولی و هومورال است و علاوه بر فعالیت همولیتیک، عملکردهای متعدد دیگری نیز دارد. این پروتئین با تخریب فاگولیزوزوم به فرار باکتری از سیتوپلاسم، زنده ماندن و رشد درون سلولیL. monocytogenes کمک می کند.از طرفی La...
متن کاملCloning, sequencing, and expression of the pyruvate carboxylase gene in Lactococcus lactis subsp. lactis C2.
A functional pyc gene was isolated from Lactococcus lactis subsp. lactis C2 and was found to complement a Pyc defect in L. lactis KB4. The deduced lactococcal Pyc protein was highly homologous to Pyc sequences of other bacteria. The pyc gene was also detected in Lactococcus lactis subsp. cremoris and L. lactis subsp. lactis bv. diacetylactis strains.
متن کاملGene expression in Lactococcus lactis.
Lactic acid bacteria are of major economic importance, as they occupy a key position in the manufacture of fermented foods. A considerable body of research is currently being devoted to the development of lactic acid bacterial strains with improved characteristics, that may be used to make fermentations pass of more efficiently, or to make new applications possible. Therefore, and because the l...
