TAL effector protein PthXo1 - B2SU53 (PTHX1_XANOP)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for B2SU53: 1
Avirulence protein. Acts as a transcription factor in rice, inducing expression of a number of host genes including SWEET11 (Os8N3, XA13, AC Q6YZF3) in susceptible plants with the Xa13 allele. Plants with the xa13 allele, which has an altered promoter, are resistant to bacterial blight caused by this bacterial strain and do not induce SWEET11. The xa13 allele elicits an atypical hypersensitive response (HR). PthXo1 binds SWEET11 promoter DNA in a sequence-specific manner. UniProt

The central DNA-binding region is composed of 23.5 tandem core repeats with 1 base-specifying residue (BSR residue 13, also called the repeat variable diresidue, RVD, residues 12 and 13) each of which recognizes 1 base in the target DNA. The BSR is the only residue which contacts DNA in a sequence-specific manner. UniProt

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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
