Molecular characterization of the nitrite-reducing system of Staphylococcus carnosus.
Characterization of a nitrite reductase-negative Staphylococcus carnosus Tn917 mutant led to the identification of the nir operon, which encodes NirBD, the dissimilatory NADH-dependent nitrite reductase; SirA, the putative oxidase and chelatase, and SirB, the uroporphyrinogen III methylase, both of which are necessary for biosynthesis of the siroheme prosthetic group; and NirR, which revealed n...
متن کاملSecretome analysis revealed adaptive and non-adaptive responses of the Staphylococcus carnosus femB mutant
FemABX peptidyl transferases are involved in non-ribosomal pentaglycine interpeptide bridge biosynthesis. Here, we characterized the phenotype of a Staphylococcus carnosus femB deletion mutant, which was affected in growth and showed pleiotropic effects such as enhanced methicillin sensitivity, lysostaphin resistance, cell clustering, and decreased peptidoglycan cross-linking. However, comparat...
متن کاملSurface display of the cholera toxin B subunit on Staphylococcus xylosus and Staphylococcus carnosus.
The heterologous surface expression of the cholera toxin B subunit (CTB) from Vibro cholerae in two staphylococcal species, Staphylococcus xylosus and Staphylococcus carnosus, has been investigated. The gene encoding native CTB (103 amino acids) was introduced into gene constructs encoding chimeric receptors designed to be translocated and anchored on the outer cell surface of the staphylococci...
متن کاملComplete Genome Sequence of Staphylococcus carnosus LTH 3730
Specific strains of the apathogenic coagulase-negative species Staphylococcus carnosus are frequently used as meat starter cultures, as they contribute to color formation and the production of aroma compounds. Here, we report the complete genome sequence of S. carnosus LTH 3730, a strain isolated from a fermented fish product.
متن کاملComplete nucleotide sequence of the lipase gene from Staphylococcus hyicus cloned in Staphylococcus carnosus.
The lipase gene from Staphylococcus hyicus subsp. hyicus was cloned in Staphylococcus carnosus and Escherichia coli. In both host organisms the lipase gene is expressed and the enzyme is released to the medium. The cloned DNA insert is 2.5 kb in length and DNA sequencing has revealed the location of the gene, the ribosomal binding site and the presence of a typical signal sequence. The open rea...
