The nature, intergeneric distribution and biosynthesis of isoprenoid quinones and phenols in gram-negative bacteria.
1. Twenty-two aerobically grown Gram-negative bacteria were analysed for demethylmenaquinones, menaquinones, 2-polyprenylphenols, 6-methoxy-2-polyprenylphenols and ubiquinones. 2. All the eight enterobacteria and both the two facultative organisms (Aeromonas punctata and Aeromonas hydrophila) examined contain all the compounds listed above. The principal homologues are octaprenyl; in addition l...
متن کاملIsoprenoid quinones of the genus Legionella.
Representative strains of each of the named species of Legionella were examined for isoprenoid quinones by reverse-phase thin-layer chromatography. All strains contained three or more ubiquinones (Q9, Q10, Q11, Q12, Q13) which were useful for placing the species into one of three distinct groups. Group 1 contained L. longbeachae, L. bozemanii, L. dumoffi, and L. gormanii; group 2 contained only...
متن کاملIsoprenoid quinones in the classification of coryneform and related bacteria.
Menaquinones were the only isoprenoid quinones found in 85 of the 95 coryneform bacteria examined. Dihydromenaquinones having nine isoprene units were the main components isolated from Corynebacterium bovis, from other glutamic acid-producing strains, and from Arthrobacter globiformis and related species. Dihydromenaquinones with eight isoprene units were found in Brevibacterium linens, the rem...
متن کاملIsoprenoid biosynthesis in Plasmodium falciparum.
Malaria kills nearly 1 million people each year, and the protozoan parasite Plasmodium falciparum has become increasingly resistant to current therapies. Isoprenoid synthesis via the methylerythritol phosphate (MEP) pathway represents an attractive target for the development of new antimalarials. The phosphonic acid antibiotic fosmidomycin is a specific inhibitor of isoprenoid synthesis and has...
متن کاملNovel bisphosphonates as inhibitors of isoprenoid biosynthesis
Statins and nitrogenous bisphosphonates (NBPs) are clinically used inhibitors of the mevalonate pathway, which is the pathway responsible for cholesterol production as well as other isoprenoid-derived molecules. Through the inhibition of HMGCR and FDPS, respectively, these drugs deplete cells of FPP and can disrupt downstream cellular processes such as protein prenylation. At the major branch p...
