UDP-N-acetylmuramoylpentapeptide-lysine N(6)-alanyltransferase - Q9EY50 (FEMX_WEIVI)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for Q9EY50: 7
Involved in the synthesis of the bacterial cell wall. Catalyzes the addition of alanine into the interchain peptide bridge of peptidoglycan precursor using aminoacyl-tRNA(Ala) as amino acid donor. This alanine is added to the epsilon-amino group of the L-lysine of the peptidoglycan UDP-N-acetyl-alpha-D-muramoyl-L-alanyl-D-glutamyl-L-lysyl-D-alanyl-D-alanine, in a ribosome-independent mechanism (PubMed:11083873, PubMed:4248527, PubMed:12679335, PubMed:15901708, PubMed:23744707). Specific for UDP-N-acetyl-muramoyl-pentapeptide. Has no activity toward UDP-N-acetyl-muramoyl-tetrapeptide or UDP-N-acetyl-muramoyl-tripeptide (PubMed:15901708). Also acts on L-seryl-tRNA(Ser) (PubMed:4248527). (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 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
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).
