Spore coat proteins

Class I

  • these proteins completly cover the membrane around the forespore
  • early localizing spore coat proteins

Class II

  • these proteins localize simultaneously with the class I proteins but begin to encase the spore only after engulfment is complete
  • early localizing spore coat proteins

Class III

  • these proteins localize simultaneously with the class I and class II proteins but start to encase the spore only after the appearance of phase dark spores (hr 4.5)
  • early localizing spore coat proteins

Class IV

  • late localizing spore coat proteins (only after completion of engulfment)
  • intermediate between classes III and V

Class V

  • late localizing spore coat proteins (only after completion of engulfment)
  • localize exclusively to phase dark spores
  • localize simultaneously to both poles of the spore

Class VI

  • late localizing spore coat proteins (only after completion of engulfment)
  • most delayed initial localization
  • localize excluseively to phase bright spores

Important web site: SporeWeb

  • SporeWeb is a dynamic web-based platform describing all stages of sporulation in B. subtilis from a gene regulatory point of view. The website is intended for all microbial researches interested in bacterial sporulation and/or gene regulatory networks and contains useful information for both sporulation experts and non-experts.
  • You can find:
    • detailed review-like descriptions of all sporulation stages,
    • schematic representations of regulatory events during every stage,
    • links to specific regulators and their regulons,
    • access to detailed Excel sheets of all sporulation-specific regulons,
    • Cytoscape-generated layouts of regulon interactions during a specific stage,
    • a tool to generate your own Cytoscape interaction figure for specific genes of interest,
    • heat maps showing expression values of all sporulation genes during the sporulation cycle (derived from Nicolas et al., 2012),
    • direct links to other knowledge platforms, such as SubtiWiki,
    • an extensive list of references for further detailed information.
  • The website is self explanatory, but you can also take a quick look at the short introduction video.
  • Importantly, the website is database driven: it can (and will) be updated as new exciting insights become available in literature.
