Serine recombinase gin - P03015 (GIN_BPMU)

 

Protein Feature View of PDB entries mapped to a UniProtKB sequence  

Number of PDB entries for P03015: 2
 
Function
Performs inversion of a viral 3 kp segment (G-segment) that encodes two alternate pairs of tail fiber proteins thereby modifying the host specificity of the virus. Binds as a dimer to the viral gix sites which are 34-bp palindromic sequences that flank the invertible G-segment. Catalyzes site-specific recombination in the presence of the host factor Fis. Gin dimers bound to each of the gix sites and host factor Fis bound to the enhancer come together to form the synaptic complex. Each Gin monomer introduces a nick and becomes covalently attached to the 5'-phosphate of the DNA, resulting in double-stranded staggered breaks at both recombination sites. A 180 degrees rotation of one of the two Gin dimers followed by religation of the DNA leads to the inversion of the G-segment (G+ or G- orientation). (data source: UniProt  )
Subunit structure
Homodimer. During inversion, two dimers associate to form a homotetramer. (data source: UniProt  )
Domain
The dimerization region is in the N-terminus. (data source: UniProt  )

Data origin/color codes
The vertical color bar on the left side indicates data provenance.
Data in green originates from UniProtKB  
Data in yellow originates from Pfam  , by interacting with the HMMER3 web site  
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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
Data in red indicates combined ranges of Homology Models from SBKB   and the Protein Model Portal  

The PDB to UniProt mapping is based on the data provided by the EBI SIFTS project. See also Velankar et al., Nucleic Acids Research 33, D262-265 (2005).
