Modulation of Cysteine Biosynthesis in Chloroplasts of Transgenic Tobacco Overexpressing Cysteine Synthase [O-Acetylserine(thiol)-Iyase]
TLDR
The results suggested that overaccumulated foreign CSase in chloroplasts could modulate biosynthetic flow of cysteine in response to sulfur stress. Expand
Enzymic synthesis of non-protein β-substituted alanines and some higher homologues in plants
Abstract Naturally occurring heterocyclic β -substituted alanines such as l -quisqualic acid and β -(pyrazol-1-yl)- l -alanine are enzymatically synthesized from O -acetyl- l -serine (OAS) andExpand
Molecular Cloning and Characterization of a Plant Serine Acetyltransferase Playing a Regulatory Role in Cysteine Biosynthesis from Watermelon (*)
TLDR
A multi-enzyme complex was formed from recombinant proteins of SATase and cysteine synthase and O-acetylserine(thiol)-lyase from watermelon, suggesting efficient metabolic channeling from serine to Cysteine, preventing the diffusion of intermediary O- acetyl-L-serine. Expand
Purification and properties of β-cyano-l-alanine synthase from Spinacia oleracea
Abstract β-Cyano- l -alanine synthase was purified ca 6200-fold to homogeneity from the leaves of spinach ( Spinacia oleracea ). The purified enzyme has an apparent M r of 60 000 and can beExpand
Isolation and characterization of cDNA that encodes a putative mitochondrion-localizing isoform of cysteine synthase (O-acetylserine(thiol)-lyase) from Spinacia oleracea.
TLDR
The cDNA clones that encode a putative mitochondrion-localizing isoform of cysteine synthase were isolated from spinach and showed the presence of one or two copies of cysC gene in the genome of spinach, which suggested that the expression level of cYSC gene was lower than those ofcysA and cysB and that the mode of ccyC expression was constitutive in green and etiolated seedlings of spinach.

Purification and properties of β-cyano-l-alanine synthase from Lathyrus latifolius☆
Abstract β-Cyano- l -alanine synthase was purified ca 470-fold to homogeneity from the aerial parts of Lathyrus latifolius. The purified enzyme has an apparent Mr of 56 000 and can be dissociatedExpand
Transgenic herbicide-resistant Atropa belladonna using an Ri binary vector and inheritance of the transgenic trait
TLDR
A successful application of transformation with an Ri plasmid binary vector for conferring an agronomically useful trait to medicinal plants is presented. Expand
Chapter 1 Lupine Alkaloids
TLDR
Although there is at present no useful drug derived from the lupine alkaloids, except for (+)-sparteine that serves as an oxytociduterotonic, the newly found pharmacological properties of the l upine alkAloids are found. Expand
Entadamide C. a sulphur-containing amide from Entada phaseoloides
Abstract A third new sulphur-containing amide, entadamide C, has been isolated from the leaves of Entada phaseoloides together with entadamide A. The stereostructure including the absoluteExpand
