• Early studies on nonsense mutants of phage phi6 suggested that the major envelope protein P9 and the non-structural protein P12 are the only proteins needed for phi6 virion envelopment [ 23 ]. (biomedcentral.com)
  • Proteins from the mutants and from wild-type cells were compared by two-dimensional polyacrylamide gel electrophoresis, and the only observed difference was in the surface antigen V-1. (lookformedical.com)
  • Proteomic analysis of secreted membrane vesicles of archaeal Sulfolobus species reveals the presence of endosome sorting complex components. (appmicro.org)
  • In spite of structural differences in cell envelope, both Gram-positive and negative bacteria produce MVs that contain the cell membrane of each bacterial species. (appmicro.org)
  • The cystovirus Pseudomonas phage phi6 has an envelope that harbors five viral membrane proteins and phospholipids derived from the cytoplasmic membrane of its Gram-negative host. (biomedcentral.com)
  • The genomes of most virus species have overlapping genes--two or more proteins coded for by the same nucleotide sequence. (nih.gov)
  • Proteins found in any species of virus. (lookformedical.com)
  • Many Lupus patients have little or no detectable perturbations in representation of the #Lachnospiraceae family or abundance of #Ruminococcus gnavus species overtime. (metabiom.org)
  • Virulent bacteriophage and type species of the genus T4-like phages, in the family MYOVIRIDAE. (lookformedical.com)
  • A temperate inducible phage and type species of the genus lambda-like viruses, in the family SIPHOVIRIDAE. (lookformedical.com)
  • Virulent bacteriophage and type species of the genus T7-like phages, in the family PODOVIRIDAE, that infects E. coli. (lookformedical.com)
  • Upon induction (VIRUS ACTIVATION) by various agents, such as ultraviolet radiation, the phage is released, which then becomes virulent and lyses the bacterium. (lookformedical.com)
