摘要：

cDNAs encoding for two isoforms of O-acetylserine (thiol) lyase (OAS-TL), which catalyzes the synthesis of cysteine, have been isolated from Arabidopsis thaliana. Secondary structure together with expression patterns derived during photomorphogenesis indicate cellular localizations in the cytosol and plastids, thus allowing a direct comparison of compartment-specific forms within one species. The cytosolic OAS-TL complemented an E. coli auxotrophic mutant lacking cysteine synthesis. Both isoforms are represented by small gene families. They are expressed under all conditions investigated and were observed to increase in expression in plants grown with limited sulfate supply.
