WebFeb 24, 2024 · Cytochrome bd inhibition enables HM2-16F to sterilize M. tuberculosis cultures in combination with Q203 As the metabolomic profiling suggested induction of reductive stress, we next examined... WebInteraction of two redox enzymes of Escherichia coli, cytochrome bo3 and cytochrome bd-I, with ammonium sulfate/ammonia at pH 7.0 and 8.3 was studied using high-resolution respirometry and absorption spectroscopy. At pH 7.0, the oxygen reductase activity of none of the enzymes is affected by the ligand. At pH 8.3, cytochrome bo3 is inhibited by the …

Targeting the menaquinol binding loop of mycobacterial cytochrome bd ...
Webits sole terminal oxidase cytochrome bd-II was proposed to be non-electrogenic. In the present work, the ability of cytochrome bd-II to generate pmf is reexamined. Absorption and fluorescence spectros-copy and oxygen pulse methods all show that in the steady-state, cytochrome bd-II is capable of producing both electrical and chemical WebWe deleted subunits I (cydA) and II (cydB) of the Mycobacterium tuberculosis cytochrome bd menaquinol oxidase. The resulting ΔcydA and ΔcydAB mutants were hypersusceptible to compounds targeting the mycobacterial bc1 menaquinol-cytochrome c oxidoreductase and exhibited bioenergetic profiles indistinguishable from strains deficient in the ABC … WebOct 1, 2024 · Cytochrome bd-type quinol oxidase is an important metalloenzyme that allows many bacteria to survive in low oxygen conditions.Since bd oxidase is found in many prokaryotes but not in eukaryotes, it has emerged as a promising bacterial drug target.
