It is possible to inactivate the early stage of lipid A synthesis of mucosal gram negative bacteria without compromising cell viability. In particular the lpxA gene in N. meningitidis was mutated and resulting lpxA knockout mutants were found to be completely lipopolysaccharide (LPS)-deficient. The major outer membrane proteins (OMPs) were detected in normal amounts. The finding provides important implications for understanding of structure and biogenesis of the outer membrane. On a practical level, the availability of LPS-deficient mutants of pathogenic mucosal bacteria such as N. meningitidis opens up new avenues to vaccine development. It enables easy isolation of endotoxin-free purified proteins, outer membranes or even whole-cell preparations for use in immunisation.

A composition suitable for inhibiting the outgrowth of fungi is provided comprising a first ingredient which inhibits the biogenesis of a normal fungal cell wall and a second ingredient which is capable of perturbing the structure of the cellular membrane of said fungi, so that either the cellular integrity is essentially lost or cell division cannot take place, or both. The first ingredient preferably inhibits the anchorage of cell wall proteins in the cell wall of the fungi and is suitably a beta-(1,6)-glucose polysaccharide, preferably beta-gentiobiose or a pustulan fragment. The second ingredient is suitably a natural microbial membrane affecting substance (MMAS), preferably MB-21. The composition is particularly suitable as a preservative for inhibiting the outgrowth of fungi in food products, such as sauces, dressings, ketchups, and soups, but is also useful for preventing or inhibiting undesired fungal growth on other products such as personal health care products, e.g. soap bars.

Advantageously, the method and system includes transgenic plant cells via an expression vector for triterpene methyltransferase and optionally various triterpene synthase and prenyltransferase all with tags directing these enzymes to the chloroplast of the transgenic plant cells for using the chloroplast methyl erythritol phosphate (MEP) pathway in the triterpene biogenesis.

The molecular mechanisms of peroxisome biogenesis have begun to emerge: in contrast, relatively little is known about how the organelle functions as cells age. The present inventors characterized age-related changes in peroxisomes of human cells and showed that aging compromises peroxisomal targeting signal 1 (PTS1) protein import, with the critical antioxidant enzyme, catalase, especially affected. The number and appearance of peroxisomes are altered in these cells, and the organelles accumulate the PTS1-import receptor. Pex5p, on their membranes. Concomitantly, cells produce increasing amounts of the toxic metabolite, H₂O₂, and this increased load of reactive oxygen species (ROS) may further reduce peroxisomal protein import and exacerbate the effects of aging. Disclosed are novel compositions and methods for restoring catalase in peroxisomes by use of targeted catalase modified at its C-terminus and/or N-terminus, optionally in combination with polypeptides which promote cellular uptake of proteins, to prevent or overcome the changes that follows aging or that are associated with a number of diseases or disorders.

The invention discloses a method for filtering, evolving and classifying proteome and a system thereof. The method comprises the following steps of: an original data acquiring step: acquiring the genome data and the proteome data (S110) of species to be classified; a predicting step: predicting a transversal transfer gene (S120) in a genome sequence based on the genome data; a filtering step: filtering a proteome sequence (S130) corresponding to the transversal transfer gene in the proteome based on the proteome data and the transversal transfer gene; a calculating step: calculating the evolving distance (S140) between the species with the filtered proteome sequence; and an inferring step: inferring a phylogeny relation (S150) between the species by utilizing the evolving distance between the species. According to the invention, existing interference information which is caused by transversal gene transfer during deducing a biogenesis process can be eliminated so that the deduced biogenesis process is more accurate to provide a more reliable classification basis for biological evolution and classification.

A vaccine platform using a Yersinia pestis mutant synthesizing an adjuvant form lipid A (monophosphoryl lipid A, MPLA) for the increased biogenesis of bacterial outer membrane vesicles (OMVs). To enhance the immunogenicity of the OMVs, an Asd-based balanced-lethal host-vector system was constructed to oversynthesize the LcrV antigen of Y. pestis, raise the amounts of LcrV enclosed in OMVs by Type II secretion system, and eliminate harmful factors like plasminogen activator (Pla) and murine toxin from the OMVs. Vaccination with OMVs containing MPLA and increased amounts of LcrV with diminished toxicity afforded complete protection in mice against subcutaneous challenge and intranasal challenge and was significantly superior to that resulting from vaccination with LcrV/alhydrogel. Additionally, the Yersinia OMV can be used as a platform to deliver the heterologous antigens of Bacillus anthraces. Vaccination with multiantigenic self-adjuvanting bionanoparticles from Pseudomonas was also successfully tested in connection with Pseudomonas aeruginosa.
