Bacterial lipoproteins are extracellular proteins tethered to cell membranes by covalently attached lipids. Deleting the lipoprotein signal peptidase (lsp) gene in Streptomyces coelicolor results in growth and developmental defects that cannot be restored by reintroducing lsp. This led us to hypothesise that lsp is essential and that the lsp mutant we isolated previously had acquired compensato...

Three open reading frames (ORFs) were identified by a genome walking strategy in the genomes of serotype M49 group A streptococcal (GAS) strains CS101 and 591. These ORFs were located between the mga core regulon and the dipeptide permease operon. The deduced amino acid (aa) sequences contained signature sequences indicative of a lipoprotein (306 aa), an intracellular protein (823 aa), and a se...

In compiling both Language for Specific Purposes (LSP) word lists foreign language learners and LSP dictionaries, the headword-selection process is of paramount importance. dictionaries will function effectively if they contain appropriate terms register items, i.e. lexical items that end users need. this paper, we first present corpus-based lists, with special emphasis on how were compiled. pr...

A strain of Chang cells. derived from a human liver line, was examined for the presence of a liver-specific membrane protein (LSP). as described by Meyer zum Buschenfelde. Indirect immunofluorescence and antisera to human. rat, and rabbit LSP were used to demonstrate that LSP was present on isolated human, rat. and rabbit hepatocytes but not on the Chang cells. The results indicate that these C...

We consider minimal supergravity (mSUGRA) models with an additional R-parity violating operator at the grand unification scale. This can change the supersymmetric spectrum leading on the one hand to a sneutrino, smuon or squark as the lightest supersymmetric particle (LSP). On the other hand, a wide parameter region is reopened, where the scalar tau is the LSP. It is vital to know the nature of...
