Defining 10 Unknown Biological Terms from Parkhill et al.

  1. Pseudogenes
    • Pseudogenes are genomic DNA sequences similar to normal genes but non-functional; they are regarded as defunct relatives of functional genes.
    • Citation: http://pseudogene.org/background.php
  2. Fimbriae
    • Modern term for short, hair-like projections or appendages (organelles) on the outer surface of certain bacteria composed of protein subunits (pilin) extending outward from the surface that act as a virulence factor by promoting adherence; formerly known as pili.
    • Citation: http://www.life.umd.edu/classroom/bsci424/Definitions.htm
  3. Auxotrophy
  4. Ortholog
  5. Insertion Sequence Elements (ISEs)
    • Insertion sequences, or insertion-sequence (IS) elements, are now known to be segments of bacterial DNA that can move from one position on a chromosome to a different position on the same chromosome or on a different chromosome. When IS elements appear in the middle of genes, they interrupt the coding sequence and inactivate the expression of that gene.
    • Citation: http://www.ncbi.nlm.nih.gov/books/NBK21779/
  6. Horizontal Gene Transfer
  7. Prophage
  8. Autotransporter
    • The key feature of an autotransporter is that it contains all the information for secretion in the precursor of the secreted protein itself. Autotransporters comprise three functional domains: 1) an N-terminal targeting domain (amino-terminal leader sequence) that functions as a signal peptide to mediate targeting to and translocation across the inner membrane 2) a C-terminal translocation domain (carboxy-terminal) that forms a beta-barrel pore to allow the secretion of 3) the passenger domain, the secreted mature protein.
    • Citation: https://www.ebi.ac.uk/interpro/entry/IPR006315
  9. Type-III Secretion System
    • The protein Type III Secretion System (T3SS) is a supramolecular, organic nanomachine that injects bacterial virulence proteins into eukaryotic cells to modulate their physiology for the benefit of the pathogen.
    • Citation: http://lab.rockefeller.edu/stebbins/research/T3SS
  10. Constitutive Expression
