Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for P18891: 4
 
Function
Lectin that specifically binds to L-fucose (PubMed:2193930, PubMed:2666154, PubMed:7397108, PubMed:18493851, PubMed:21945439, PubMed:27650323, PubMed:28800497, PubMed:14503859, PubMed:12732625). Has strongest preference for the alpha-1,6-fucosylated chain (core fucose) on glycoproteins among alpha-1,2-, alpha-1,3-, alpha-1,4-, and alpha-1,6-fucosylated chains (PubMed:17383961, PubMed:19109923, PubMed:20798114, PubMed:22226468). Might play a role in the differentiation of the fruiting body (PubMed:2193930). Exhibits antifungal activity against Mucor racemosus and thus could act as an antifungal protein in natural ecosystems (PubMed:22738968). UniProt

Subunit Structure
Forms homodimers (PubMed:2193930, PubMed:7397108, PubMed:20798114, PubMed:12732625). The two AAL monomers are associated via interactions between N-terminal and C-terminal peptides (PubMed:12732625). Tyr-7 interacts via aromatic ring stacking with its counterpart on the other monomer, whereas Ser-284 interacts via hydrogen bonding with Asp-264 on the other monomer (PubMed:12732625). UniProt
Domain
AAL adopts the six-bladed beta-propeller fold and contains 5 binding sites per monomer, each located between two adjacent blades (PubMed:14503859, PubMed:12732625). Residues conserved at 5 of the 6 sites, are located on the surface of the AAL and directly contribute to fucose recognition (PubMed:14503859). Because the corresponding residues forming site 6 are not conserved, this site cannot be considered to accommodate fucose molecules (PubMed:14503859). The 5 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:18493851, PubMed:12732625).

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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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