General Information

EC Number General Information Comment Organism
2.5.1.90 malfunction it is impossible to obtain an ispB deletion mutant unless the ispB gene or its homolog is supplied on a plasmid. The ispB gene is essential for the normal growth of Escherichia coli Escherichia coli
2.5.1.90 physiological function octaprenyl diphosphate synthase is responsible for the synthesis of the side chain of isoprenoid quinones Escherichia coli
2.5.1.90 physiological function the chromosomal ispB disrupted mutant cannot be isolated unless the ispB gene or its homolog is supplied on a plasmid. The chromosomal ispB disruptants that harbor plasmids carrying the ispB homologs from Haemophilus influenzae and Synechocystis sp. strain PCC6803 produce mainly ubiquinone 7 and ubiquinone 9, respectively Escherichia coli K-12
