Description

HQNO, secreted by P. aeruginosa, is a potent electron transport chain inhibitor with a Kd of 64 nM for complex III[1]. HQNO is a potent inhibitor of mitochondrial NDH-2 in many species[2].

IC50 & Target

NDH-2[2]

In Vitro

HQNO is a potent inhibitor of mitochondrial type II NADH:quinone oxidoreductase (NDH-2) in many species, including Yarrowia lipolytica, S. cerevisiae, Gluconobacter oxydans, T. gondii, P. falciparum, and S. aureus. HQNO targets the Q-site of NDH-2[2].
HQNO concentrations are varied from 0 to 100 μM and 0 to 300 μM for wild-type (WT) and I379E C. thermarum NDH-2 variant, respectively to determine IC50 values. WT NDH-2 has an IC50 value of 10.5±1.3 μM HQNO in the presence of 400 μM Menadione (MD). In the presence of 50 μM MD, the IC50 value for HQNO decreases slightly to 7.3±1.2 μM and near complete inhibition (~15% residual activity) is observed with >50 μM HQNO. At 50 μM MD, HQNO inhibition is observed with an IC50 value of 54.3±1.2 μM[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
