摘要: Publisher Summary This chapter discusses sulfur amino acids in plants. Most of the inorganic sulfate assimilated and reduced by plants appears ultimately cysteine methionine. These contain about 90% total most Nearly all methionine is protein. The highlights typical dominance protein organic sulfur. In nonprotein fraction, glutathione (GSH) ubiquitous commonly a major constituent. soluble fraction also includes variety other sulfur-containing compounds that are normally present relatively small amounts: (1) intermediates on route to methionine, such as cysteine, cystathionine, homocysteine, (2) involved methyl transfer reactions polyamine synthesis AdoMet, AdoHcy, 5'-methyl-thioadenosine. Cysteine precursor GSH, moiety is, therefore, portal for Serine source C3
