Baseplate central spike complex protein gp5 - P16009 (BP5_BPT4)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for P16009: 11
Baseplate central spike complex-associated lysozyme that is essential for the localized hydrolysis of bacterial cell wall in the periplasmic space, a necessary step for viral DNA ejection into the host cell. Involved in the tail assembly. UniProt
Catalytic Activity
Hydrolysis of 1->4-beta-linkages between N-acetylmuramic acid and N-acetyl-D-glucosamine residues in a peptidoglycan and between N-acetyl-D-glucosamine residues in chitodextrins. UniProt

Subunit Structure
Homotrimer (PubMed:12837775, PubMed:19896486, PubMed:11823865). Heteromultimer with gp27 trimer and gp5.4 monomer; this interaction forms the central spike complex that creates an extension of the tail tube (PubMed:12837775, PubMed:27193680). The central spike complex is made up of three copies of the gp27-gp5*-gp5C complex and one copy of gp5.4 (PubMed:11823865, PubMed:27193680). Part of the baseplate macromolecular complex which consists of gp5, gp5.4, gp27 (central spike complex); gp6, gp25, gp53 (inner baseplate); gp7, gp8 (intermediate baseplate); gp9, gp10, gp11, gp12 (peripheral); gp48 and gp54 (proximal region of the tail tube) (PubMed:27193680).

Data origin/color codes
The vertical color bar on the left side indicates data provenance.
Data in green originates from UniProtKB  
Variation data (sourced from UniProt) shows non-genetic variation from the ExPASy   and dbSNP   websites.
Data in yellow originates from Pfam  , by interacting with the HMMER3 web site  
Data in purple originates from Phosphosite  .
Data in orange originates from the SCOP   (version 1.75) and SCOPe   (version 2.04) classifications.
Data in grey has been calculated using BioJava  . Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  
  • Red: potentially disorderd region
  • Blue: probably ordered region.
Hydropathy has been calculated using a sliding window of 15 residues and summing up scores from standard hydrophobicity tables.
  • Red: hydrophobic
  • Blue: hydrophilic.
Data in lilac represent the genomic exon structure projected onto the UniProt sequence.
Data in blue originates from PDB
  • Secstruc: Secondary structure projected from representative PDB entries onto the UniProt sequence.
Sequence Mismatches It is now possible to see information about expression tags, cloning artifacts, and many other details related to sequence mismatches.
Icons represent a number of different sequence modifications that can be observed in PDB files. For example the 'T' icon T represents expression tags that have been added to the sequence. The 'E' icon E represents an engineered mutation. However, besides these two, there are many other icons. For more information about the meaning and exact position of a sequence modification, move the cursor over the icon.
