Disease relevance of adhA

  • To understand the role of the heme c moieties in the intramolecular electron transport and the ubiquinone reduction, the ADH complex of Gluconobacter suboxydans was separated into a subunit I/III complex and subunit II, then reconstituted into the complex [1].
  • Hybrid ADH consisting of the subunit I/III complex of G. suboxydans ADH and subunit II of Acetobacter aceti ADH was constructed and it had showed a significant Q1 reductase activity, indicating that subunit II has a ubiquinone-binding site [1].
  • Cell-free extracts of Pseudomonas aeruginosa strains, grown on ethanol, showed dye-linked alcohol dehydrogenase activities [2].
  • It is a homodimeric enzyme and, aside from differences in some loops, the folding of QEDH is very similar to the large subunit of the soluble methanol dehydrogenase of methylotrophs, and the PQQ domain of the quinohemoprotein alcohol dehydrogenase from Comamonas testosteroni and P. fluorescens [3].
 

High impact information on adhA

  • Using these active and inactive ADHs and also isolated subunit I/III complex, we performed kinetic studies which suggested that ADH contains four ferricyanide-reacting sites, one of which was detected in subunit I and the others in subunit II [1].
  • Function of multiple heme c moieties in intramolecular electron transport and ubiquinone reduction in the quinohemoprotein alcohol dehydrogenase-cytochrome c complex of Gluconobacter suboxydans [1].
  • ADH is a membrane-bound quinohemoprotein-cytochrome c complex which consists of subunits I (78 kDa), II (48 kDa), and III (14 kDa) and contains several hemes c as well as pyrroloquinoline quinone as prosthetic groups [1].
  • Together with previous results on a particulate alcohol dehydrogenase enzyme (Benson and Shapiro, J. Bacteriol., 126: 794-798, 1976), these results allowed us to assay three plasmid-determined inducible activities: soluble alkane hydroxylase (alkA+), particulate alkane hydroxylase (alkB+), and particulate alcohol dehydrogenase (alkC+) [4].
  • The phosphorescence yield and decay kinetics of tryptophan (Trp) in apoazurin from Pseudomonas aeruginosa, subtilisin Carlsberg, Staphylococcal nuclease and liver alcohol dehydrogenase were determined as a function of temperature from 150 K (glassy matrix) to 300 K (fluid solution) [5].
