Mannosylglycerate synthase - Q9RFR0 (MGS_RHOMR)

 

Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for Q9RFR0: 5
 
Function
Involved in the biosynthesis of the stress protectant 2-O-alpha-D-mannosyl glycerate (MG) which is produced in response to growth at supraoptimal temperature and salinity, and protects several enzymes against inactivation by temperature, freeze-drying and osmotic stress. Catalyzes the condensation of alpha-GDP-D-mannose (GDP-Man) with D-glycerate to produce alpha-mannosyl-D-glycerate. It is specific for GDP-Man, but it can also use alpha-GDP-D-glucose (GDP-Glc), beta-GDP-D-fructose, alpha-UDP-D-mannose and alpha-UDP-D-glucose as sugar donors. It is specific for D-glycerate, but it can also use D-lactate and glycolate as sugar acceptors. This reaction occurs with a net retention of anomeric configuration; the newly formed glycosidic linkage has the same alpha configuration as the sugar donor. UniProt

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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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