  • Although the majority of natural circular RNAs are non-coding RNAs, meaning they cannot be translated into proteins, research has shown that artificially synthesized circular RNAs with internal ribosome entry site (IRES) sequences can be translated both in vivo and in vitro. (techadda2.com)
  • DNA sequences that form the coding region for the viral envelope (env) proteins in retroviruses. (lookformedical.com)
  • Complex or Atypical - Example: Bacteriophage, Vaccinia virus. (brainkart.com)
  • Their proteomes are highly unstudied, with over 200 putative proteins with no known homologs. (frontiersin.org)
  • The production of 27 of these putative proteins was confirmed by mass spectrometry analysis. (frontiersin.org)
  • Analyses of the proteins encoded within this region by ΦSH19 revealed a cluster of three putative tail spikes. (biomedcentral.com)
  • Tail spike proteins of Vi01 and SboM-AG3 are predicted to contain conserved right-handed parallel β-helical structures but the internal protein domains are varied allowing different host specificities. (biomedcentral.com)
  • They are usually synthesized as protein precursors (POLYPROTEINS) and later cleaved into the final viral envelope glycoproteins by a viral protease. (lookformedical.com)
  • 1996) Gene 174: 315-318) flanked with the reset cells, fitting multivariate. (scoutconnection.com)
  • Upon binding to the host cell surface, the baseplate changes its conformation and triggers sheath contraction, driving the rigid internal tail tube through the cell envelope. (expasy.org)
  • It is of fundamental importance in determining PROTEIN CONFORMATION. (lookformedical.com)
  • A virus may pickup gene of the host in place of its own gene during its multiplication in the host cell. (qforquestions.in)
  • Homologs of several vB_OliS_GJ44 genes have mostly been found in marine metagenomes, suggesting the prevalence of this phage genus in the oceans. (biomedcentral.com)
  • The morphological features of a typical bacteriophage include a distinct head, which houses the nucleic acid, and a tail apparatus. (microbiologynote.com)
  • In essence, this is the packaging of bacterial DNA into a viral envelope. (tedxhongkong.org)
  • Retroviral proteins, often glycosylated, coded by the envelope (env) gene. (lookformedical.com)
  • External envelope protein of the human immunodeficiency virus which is encoded by the HIV env gene. (lookformedical.com)
  • The envelope consists of an inner layer of lipids and virus specified proteins also called membrane or matrix proteins. (lookformedical.com)
  • Transmembrane envelope protein of the HUMAN IMMUNODEFICIENCY VIRUS which is encoded by the HIV env gene. (lookformedical.com)
  • It serves as a precursor for both the HIV ENVELOPE PROTEIN GP120 and the HIV ENVELOPE PROTEIN GP41 . (lookformedical.com)
