Light-independent protochlorophyllide reductase iron-sulfur ATP-binding protein - Q7VD39 (CHLL_PROMA)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

Number of PDB entries for Q7VD39: 1
Component of the dark-operative protochlorophyllide reductase (DPOR) that uses Mg-ATP and reduced ferredoxin to reduce ring D of protochlorophyllide (Pchlide) to form chlorophyllide a (Chlide). This reaction is light-independent. The L component serves as a unique electron donor to the NB-component of the complex, and binds Mg-ATP. (data source: UniProt  )
Catalytic Activity

Protochlorophyllide a + reduced ferredoxin + 2 ATP + 2 H(2)O = chlorophyllide a + oxidized ferredoxin + 2 ADP + 2 phosphate.

(data source: UniProt  )
Subunit structure
Homodimer. Protochlorophyllide reductase is composed of three subunits; ChlL, ChlN and ChlB. (data source: UniProt  )
Gene names: chlL Pro_0544

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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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