Putative diacylated glycolipid transporter LprF - P65315 (LPRF_MYCBO)

 

Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for P65315: 1
 
Function
Might be involved in transporting short diacylated glycolipids to the cell outer membrane. Binds glycolipids that contain a diacylated glycerophosphate or a diacylated phosphatidylinositol moiety with C14 and C16 chains (upon overexpression in M.smegmatis; M.smegmatis does not encode this gene). Overexpression in M.smegmatis increases the cell wall glycolipid LAM/LM ratio (lipoarabinomannan/lipomannan), suggesting perhaps this protein is involved in the preferential translocation of diacylated LAM to the outer cell membrane. Overexpressing M.smegmatis cells adhere less well to hexadecane droplets, indicating decrease in the hydrophobicity of the cell surface, and have a slightly increased resistance to the antibiotic ethambutol.

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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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