NADPH-dependent thioredoxin reductase and 2-Cys peroxiredoxins are needed for the protection of Mg–protoporphyrin monomethyl ester cyclase
(2008) In FEBS Letters 582(18). p.2773-2778- Abstract
- Abstract The chloroplast-localized NADPH-dependent thioredoxin
reductase (NTRC) has been found to be able to reduce
hydrogen peroxide scavenging 2-Cys peroxiredoxins. We show
that the Arabidopsis ntrc mutant is perturbed in chlorophyll biosynthesis
and accumulate intermediates preceding protochlorophyllide
formation. A specific involvement of NTRC during
biosynthesis of protochlorophyllide is indicated from in vitro aerobic
cyclase assays in which the conversion of Mg–protoporhyrin
monomethyl ester into protochlorophyllide is stimulated by addition
of the NTRC/2-Cys peroxiredoxin system. These findings
support the hypothesis that this NADPH-dependent... (More) - Abstract The chloroplast-localized NADPH-dependent thioredoxin

chloroplast biogenesis. (Less)
