Associations of ECs0046 with chemical compounds

  • A BLAST search of protein data bases revealed that PDPr is distantly related to the mitochondrial flavoprotein dimethylglycine dehydrogenase, which functions in choline degradation [21].
  • In addition, three previously identified NPXase segments, known to be involved in FAD and NAD(P)-binding in other pyridine nucleotide-linked flavoprotein oxidoreductases, are strongly conserved in NOXase [3].
  • Four crystal structures of the 60 kDa flavoprotein monomer of the sulfite reductase indicate a disordered flavodoxin-like module [22].
  • The recombinant protein was purified by affinity chromatography on guazatine-Sepharose 4B and was shown to be a flavoprotein able to oxidize Spm, norspermine, and N1-acetylspermine with a pH optimum at 8 [23].
  • MTOX forms an anionic flavin semiquinone and a reversible, covalent flavin-sulfite complex (K(d) = 1.7 mM), properties characteristic of flavoprotein oxidases [24].
 

Other interactions of ECs0046

 

Analytical, diagnostic and therapeutic context of ECs0046

  • B. amyloliquefaciens YwrO was shown to be a flavoprotein with a monomeric molecular mass of 21.5 kDa by calculation and SDS-PAGE [27].
  • NADPH-cytochrome P450 reductase (CPR) is a membrane-bound flavoprotein that interacts with the membrane via its N-terminal hydrophobic sequence (residues 1-56) [28].
  • In the present work, by replacement of the lysine residue (Lys56) with Gln using site directed mutagenesis, we prepared the full-length flavoprotein mutant Lys56Gln stable to spontaneous proteolysis but possessing spectral and catalytic properties of the wild type flavoprotein [28].
