Cysteine is the first organic product of sulfate assimilation and as such is the precursor of all molecules containing reduced sulfur including methionine, glutathione, and their many metabolites. In plants, 5'-adenylylsulfate (APS) reductase is hypo

Summary b-Zein is one of the seed storage proteins of maize that is high in methionine (Met). In alfalfa, the b-zein gene driven by the CaMV 35S promoter showed an 8-fold lower level of transcript and protein when compared with the level in tobacco t

*† Summary Homoserine kinase (HSK) produces O-phospho-L-homoserine (HserP) used by cystathionine c-synthase (CGS) for Met synthesis and threonine synthase (TS) for Thr synthesis. The effects of overexpressing Arabidopsis thaliana HSK, CGS, and Esch

The two-electron reduction of sulfate to sulfite in plants is mediated by 5'-adenylylsulfate (APS) reductase, an enzyme theorized to be a control point for cysteine synthesis. The hypothesis was tested by expression in Arabidopsis thaliana under tran

The physiological role of the NADH-dependent glutamine-2-oxoglutarate aminotransferase (NADH-GOGAT) enzyme was addressed in Arabidopsis using gene expression analysis and by the characterization of a knock-out T-DNA insertion mutant (glt1-T) in the s

The committing step in Met andS-adenosyl-l-Met (SAM) synthesis is catalyzed by cystathionine γ-synthase (CGS). Transgenic Arabidopsis plants overexpressing CGS under control of the cauliflower mosaic virus 35S promoter show increased soluble Met and

Intracellular transport of the ethylene precursor, I-aminocyclopropane-1-carboxylic acid (ACC) can change the ACC concentration in cell compartments and impact ethylene biosynthesis. Transport of ACC into isolated maize (Zea mays L.) mesophyll vacuol

γ-Glutamyl transpeptidases (GGTs) are essential for hydrolysis of the tripeptide glutathione (γ-glutamate-cysteine-glycine) and glutathione S-conjugates since they are the only enzymes known to cleave the amide bond linking the γ-carboxylate of gl

▪ Abstract Sulfur is essential for life. Its oxidation state is in constant flux as it circulates through the global sulfur cycle. Plants play a key role in the cycle since they are primary producers of organic sulfur compounds. They are able to co
