Disease relevance of SF-1902A1

  • Cleavage of the pilin leader peptide is independent of known signal peptidases as demonstrated by pilin-processing profiles in Escherichia coli strains conditionally defective for production of leader peptidase or grown in the presence of the antibiotic globomycin [1].
  • The lipoprotein nature of FatB is supported by the fact that treatment of Vibrio anguillarum cells with globomycin, an inhibitor of the lipoprotein signal peptidase, results in the accumulation of a 38 kDa proFatB precursor protein [2].
  • In the current study, we showed that the product of the cloned gene could be labelled with palmitic acid, that it was subject to globomycin-sensitive processing, and that it was immunologically cross-reactive with azurin from Pseudomonas aeruginosa [3].
  • The use of the antibiotic globomycin in a minicell expression system and radioimmunoprecipitation analysis of Hib proteins intrinsically radiolabelled with [3H]-palmitate indicated that the 51K haemin-binding protein is a lipoprotein [4].
  • When the mycoplasma cell concentration was varied from 10(4) to 10(8) CFU/ml, the MICs of enrofloxacin and globomycin increased while those of the three other molecules remained essentially constant [5].
 

High impact information on SF-1902A1

  • Under the same conditions, globomycin does not prevent the attachment of palmitate or glycerol to the E. coli prolipoprotein but inhibits processing of the modified precursor to the mature lipoprotein [6].
  • The peptide antibiotic globomycin, which prevents processing of the E. coli prolipoprotein, severely inhibited the attachment of [3H]palmitate or [3H]glycerol to the 749/C enzyme (either in B. licheniformis 749/C or in E. coli), blocked the accumulation of penicillinase in the plasma membrane, and enhanced the formation of exoenzyme [6].
  • These results are in contrast with the lack of effect of globomycin on the RTEM-beta-lactamase of E. coli which has no detectable hydrophobic membrane form and was not labeled with palmitate or glycerol [6].
  • Overexpression, membrane fractionation, and metabolic labeling with [3H]palmitate demonstrated that Blc is indeed a globomycin-sensitive outer membrane lipoprotein [7].
  • Experiments with globomycin presented here also suggest that the primary precursor of EGL (ppEGL) has a 45-residue leader sequence but that only the first 19 residues of the leader sequence are removed by signal peptidase II during initial export across the inner membrane [8].
 

Chemical compound and disease context of SF-1902A1

 

Biological context of SF-1902A1

  • The plasmid pMT521, a subclone of pLC3-13 in pBR322, conferred on its host cells approximately 20 times overproduction of prolipoprotein signal peptidase and an extremely high level of resistance against globomycin [13].
  • The incorporation of exogenous [1-14C]palmitate into phosphatidylethanolamine in fadD mutants was inhibited by chloramphenicol and was depressed by preventing the acylation of the amino terminus of the lipoproteins with the antibiotic globomycin [14].
  • Three revertants were chosen in the present study which included the analysis of kinetics of lipoprotein maturation and the determination of globomycin sensitivity [15].
  • Lipoprotein fatty acids derived from the 1-position of phosphatidylethanolamine were resistant to hydroxylamine hydrolysis, and globomycin reduced the incorporation of exogenous [1-14C]palmitate into lipoproteins by 80% suggesting that this fatty acid is primarily attached to the amino terminus of the lipoprotein [14].
  • As predicted by the DNA sequence, the recombinant 15 kiloDalton immunogen labelled selectively with [3H]-palmitate, and globomycin inhibited processing of the precursor to the mature polypeptide [16].

Analytical, diagnostic and therapeutic context of SF-1902A1

  • Immunoblotting analysis using the antibody against the 45-kDa protein revealed a 48-kDa precursor of the protein, which accumulated in the cyanobacterial cells treated with globomycin, an antibiotic that specifically inhibits cleavage of the signal peptide of lipoprotein precursors [28].
  • After treatment with globomycin, a significant amount of this modified precursor form accumulated and was degraded with time into smaller acylated proteins, but without release of the signal peptide [29].
  • SDS-PAGE analysis of cell proteins followed by immunolabeling ("Western blotting") and by crossed immunoelectrophoresis demonstrated that the cleavage of the prespiralin leader peptide was prevented by globomycin [22].
