Sulfate uptake in potato tuber discs is inhibited by cysteine and methionine with an 8 h lag period. Cysteine, but not methionine, inhibition can be reversed by washing the treated discs. During the experimental period cysteine is rapidly metabolized, while methionine persists as a free amino acid. Amino acid inhibition of sulfate uptake is overcome by increasing sulfate concentration. The kinetic parameters change suggesting a loss of flexibility of the sulfate uptake system caused by sulfur amino acids. [ABSTRACT FROM AUTHOR] |
