streptococcus arrangement

Edge evidence

• parallel division planes causes streptococcus arrangement biolink:causes

  Parallel successive division planes with incomplete daughter separation produce coccal chains.

  • DOI:10.1038/ncomms4842 Daughter-cell separation during division determines whether cocci stay attached in chains.
• cell division enables streptococcus arrangement RO:0002327

  Bacterial cell division underlies coccal chain formation.

  • DOI:10.1128/MMBR.00001-06 Young treats chain arrangement as a heritable, division-determined morphology.
• parallel division planes enables cell division RO:0002327

  Ovococci divide in successive parallel planes perpendicular to the long axis.

  • DOI:10.1128/mSphere.00119-21 Ovococci are elongated ellipsoids divided in successive parallel planes perpendicular to their long axis.
• peptidoglycan hydrolases enables peptidoglycan remodeling RO:0002327

  PG hydrolases release nascent glycan strands and cleave muropeptides, enabling PG remodeling and eventual splitting.

  • DOI:10.3389/fmicb.2021.737396 PG hydrolases are required to release nascent glycan strands and cleave muropeptides, enabling integration of new material and eventual splitting.
• PcsB autolysin promotes peptidoglycan remodeling RO:0002213

  PcsB PG remodeling activity is coordinated with cell division.

  • DOI:10.1128/mSphere.00119-21 The PG remodeling activity by PcsB is coordinated with cell division through its interaction with the FtsEX complex.
• FtsEX complex required for PcsB autolysin

  The FtsEX complex is required for PcsB autolysin function.

  • DOI:10.1128/mSphere.00119-21 PcsB is the only essential PG autolysin, and the FtsEX complex is required for the PcsB function.
• peptidoglycan remodeling promotes daughter-cell separation RO:0002213

  Septal PG remodeling/splitting enables daughter cells to separate; failure maintains chains.

  • DOI:10.1128/mSphere.00119-21 Part of the residual structure of PG did not fully disintegrate, resulting in incomplete cell separation (chain phenotype).
• daughter-cell separation prevents streptococcus arrangement RO:0002212

  Complete daughter-cell separation prevents chain formation; its failure produces chains.

  • DOI:10.1038/ncomms4842 Daughter-cell separation during division determines whether cocci stay attached in chains versus separating.
• lipoteichoic acid promotes cell division RO:0002213

  Lipoteichoic acid supports proper cell shape and bacterial division.

  • DOI:10.1186/s13567-024-01287-w LTA is involved in maintaining proper cell shape and influences cell shape and bacterial division.
