Fucose-specific lectin - Q4WW81 (LECF_ASPFU)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for Q4WW81: 8
Multispecific lectin that is able to recognize L-fucose in all possible linkages (PubMed:23695231, PubMed:27058347, PubMed:24340081, PubMed:25760594). These could be found not only in decomposed plant matter in soil, which is the natural environment for A.fumigatus, but also in various epitopes on human tissues (PubMed:25760594). Mediates binding of A.fumigatus conidia to airway mucinin a fucose dependent manner (PubMed:27058347). Stimulates IL-8 production by human bronchial cells in a dose-dependent manner, contributing to the inflammatory response observed upon the exposure of a patient to A.fumigatus, and thus might be an important virulence factor involved in an early stage of A.fumigatus infection (PubMed:24340081).

Subunit Structure
Homodimer (PubMed:25760594). UniProt
AFL adopts the six-bladed beta-propeller fold and contains 6 binding sites per monomer, each located between two adjacent blades (PubMed:25760594). The 6 binding sites that are non-equivalent, and owing to minor differences in amino-acid composition they exhibit a marked difference in specific ligand recognition (PubMed:24340081, PubMed:25760594).

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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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