1.1.1.284 formaldehyde in the presence of NAD+ and initial absence of NADH, ADH3-mediated S-nitrosoglutathione reduction is triggered by the presence of formaldehyde 696092 1.1.1.284 glutathione dependent on 742700 1.1.1.284 additional information formaldehyde induces the enzyme expression 686818 1.1.1.284 additional information the GSNOR1/HOT5/PAR2 protein level, other than its steady-state mRNA level, is induced by paraquat 703110 1.1.1.284 NADH increasing intracellular NADH levels are likely to trigger S-nitrosoglutathione reduction 697214 1.1.1.284 pyrazole no effect 287866 1.1.1.284 pyrazole stimulates 287866 1.1.1.284 S-nitrosoglutathione i.e. GSNO, kinetic activation of GSNOR by its substrate S-nitrosoglutathione (GSNO). Enzyme GSNOR kinetic analysis data results in nonhyperbolic behavior that was successfully accommodated by the Hill-Langmuir equation with a Hill coex0ecient of +1.75, indicating that the substrate, GSNO, is acting as a positive allosteric affector. GSNO activates GSNOR by binding to an allosteric site comprised of the residues Asn185, Lys188, Gly321, and Lys323 762616
